You do not see the the jobs the unemployed would have had if the money were not taxed away.
The "taxed away" part is problematic. The government spends money as fast as (or faster than) it gets it.
We know there's a flow of money between the government and the private sector. We know the private sector doesn't have any less money because of the flow. We know the amount that goes in is the same as the amount that goes out. So why should the private sector hire fewer people?
Let me turn the hypothetical around a little bit. Suppose the government spends first, and then taxes. Suppose also that there are some unemployed people who are skilled and willing to work.
Your business has not been taxed, so it doesn't fire anybody. The government, on the other hand, hires a bunch of people who otherwise wouldn't have had jobs or incomes, and puts them to work building a bridge.
The net result is $10 million worth of wages that otherwise wouldn't have been there. Plus a bridge. The bridge workers don't just keep that money, though, they spend it. They buy food, shelter, clothing, all of those things. In fact, they buy it from your business, which now has an extra $10 million of income. At the end of the year the government taxes your business $10 million, then hires the bridge workers to build a road.
In this hypothetical, no one in the private sector is worse off. The business does not have to lay off any workers. The difference is we created a bunch of jobs, and we got a bridge out of it.
The problem is where you're beginning and ending your hypothetical.
If you built a hypothetical where the sun evaporated water off the ocean, and then it rained, and then the sun evaporated more water, (and ended your hypothetical there) you'd think eventually all the water in the ocean would evaporate into the air.
If I am correct, you had two main arguments in the above.
1. If you look at it from the perspective that government spends first and then taxes, it becomes clear there is growth.
2. Workers funded by government spend their money on other goods as well, creating more jobs and hiring from my business. Thus, government spending creates more than just the jobs created by the bridge.
I will address each separately.
1. It does not matter at all whether or not you look first at spending or at taxation. If you look at spending first, all of the affects of taxation will simply come
in the future. You do not avoid taxation by borrowing, you only delay it. The situation does not change in the least. If you spend first and create the bridge, you must eventually tax to pay off the debts. The money taxed will be spent not on more jobs,
but on the previous jobs. Your scenario would only be true if government did not have to pay back debt. If the spending is instead used not to pay off the debts but to create more jobs, you will continue accumulating debt, and the future tax burden will only grow.
Again you seem to be arguing that if a dollar is taxed, that makes it unavailable to the private sector. In fact, every dollar that is taxed is also spent. No dollars ever disappear from the system.
Also, governments do not have to pay off debts. The US has had a debt since it was founded.
2. You are absolutely correct. People who obtain money through government funds will then spend that money on other goods and services, creating employment with their demand. But again you miss that those who were taxed cannot spend that money on goods and services. They would not hoard their money either. Again, there is only a transfer of who does the spending.
In my hypothetical, the business gets an extra $10,000 it would not have gotten had the government not spent it in the first place.
When the government taxes at the end of the year, it is simply taking back money it created in the first place.
Beginning on Jan 1, the private sector has an additional 10k that it would not have had but for government spending. At the end of the year, the government taxes that money back. At the end of the year, the private sector has no less money than it had before.
There is no loss of spending power anywhere in this scenario.
To illustrate the point:
Government taxes 10 million from the private sector. It then spends that 10 million to create a bridge. It is evident that any jobs created by government to build the bridge were funded at the expense of private sector jobs that could have been created had the money not been taxed away.
That's not evident at all.
1.) You're assuming there's no "extra" money in the private sector, ie, no savings.
2.) You're assuming the private sector can't borrow. In fact, businesses routinely borrow to ramp up production, if there's demand for their product.
3.) In your scenario the government takes a bunch of money and pays it out over time. That's not what governments do.
The same would be true if government spent first, the order of the affects would simply be reversed. (In fact, if government spent first, it could even be worse, because government would also have to tax interest.)
Again, the logic of your position depends on the idea that money can only be spent once.
Where does the money the government taxes for interest go?
It goes directly to the private sector. The private sector has no less money because of interest. It has no less money because of taxes. (Assuming the government spends the tax money, of course.)
Furthermore, this bridge was not really needed by anyone in the community, and was built for the sake of jobs only. The bridge is nice, and some people use it, but it is not truly necessary.
That is the initial transaction. Because government spent the money instead of the individuals who were taxed,
But the government did not spend the money instead of the people being taxed. The people being taxed get to spend the money too.
there is no net gain in wealth. Perhaps the bridge would have been created by the private sector, perhaps for less money. But since people may not have needed the bridge, money would have been spent on other sectors of the economy, producing what people actually need.
But there is a gain in wealth - the bridge. And, if you look closely, you'll see the bridge is quite useful. In fact, it's an asset, because private businesses use the bridge to do their business, and regular people use it too.
You added that bridge workers spend their money, further stimulating growth. But had the jobs funded by the private sector been allowed to come into existence, those getting paid would do the same thing. The only difference between government spending the money and the private sector spending the money is that when government spends money, it is arbitrarily spent, and not in line with consumer preference. In the private sector, spent money is inline with consumer preference because it is consumers doing the spending.
Your claim that the bridge workers now have more money to spend is meaningless, because had government not taxed away the money, different jobs would have been created, and money from those jobs would have been spent in the same fashion. Again, at best you can argue it is a zero sum game, but in reality, because of government inefficiencies, there will always be a net loss. But the loss is widespread and unseen and the benefit concentrated and visible to the eye, so people focus only on the benefit and forget the cost entirely.
Even if money worked the way you say it does - that the government spending it prevents the private sector from spending it too - which is not the case -
Businesses are not constrained by the amount of money on hand, and they don't make decisions about expanding or hiring based on how much money they have in the bank.
Businesses expand when there's demand for their products. If there's demand, they'll expand, even if they have to borrow.
If there's no demand, they won't hire, even if - as is currently the case - they have trillions in the bank.
