Republicans nit-pick over government spending while ignoring the big picture: government does what the private sector in incapable of doing.
Can the private sector protect our country? No.
Can the private sector build and maintain our roads? No.
Can it provide medical insurance to the elderly? No.
Can it educate ALL our children? No.
Can it protect the air, the water, and the land from industrial poisons? No.
Etc.
The fact is the very existence of this country depends on government, and there would be no economy without it. The argument that the private market does it better ignores the fact that the private sector doesn't do it.
Can you prove that the private sector cannot do all of those things, or do you simply assume that?
The fact is that no one I have seen on this board advocates eliminating the government, and the economy supports the government. Even Keynes preferred a smaller government to a larger one, yet every time anyone talks about making it smaller some idiot acts like making the government smaller will kill the economy because the economy depends on the government.
The truth is a bit more complicated than what I am about to say, but when it comes down to it the economy will go on forever without the government, and the government will collapse tomorrow without the economy.
The argument that the private sector doesn't do it ignores the fact that the government forbids the private sector from doing most things that it does. The USPS used to be the only game in town, and that somehow proved the private sector couldn't handle the mail. The funny thing is, no one thinks that today.
Without patents, copyrights, trademarks, corporations, roads, money, police, courts, and law it's hard to see what kind of economy we'd have. Maybe something like what they had in Mad Max?
The value of government services far exceeds what we pay for them. Sometimes that's hard to see, because the government doesn't seek to make a profit, or attempt to sell things at market rates. But mostly people just take things for granted.
I can't "prove" that the private sector can't do these things. I can only point to the fact it never has, and that typically private businesses won't do something, unless there's a way to make a profit at it.
Trust me, pointing at patents and copyrights as a way to prove we need the government to sustain the economy is not the way to go. If you drop it I will give you a pass on it, otherwise I will point out exactly how patents and copyrights are being used to stifle competition and keep innovation out of the economy.
As for government services value being higher than what we pay for them, I am not going to let that one pass. The Professional Left likes to site the fact that Medicare has a lower overhead cost than private insurance, but that is actually because of two factors. The first is that the government can transfer the cost of some of the Medicare administration so that it is off the books. It does this in multiple ways, one is to make the private sector carry some of the administrative cost by forcing them to comply with onerous reporting standards. They can also transfer some of the costs themselves to other programs, and forcing people that do not participate in Medicare to pay for it anyway. If you do not believe the latter, check with any retired military you know that use VA services and ask them about how much they pay to Medicare annually.
Another thing that Medicare does is report its administrative costs as a percentage of their entire budget. When you do a per patient comparison Medicare is actually more expensive than private insurance. This is actually interesting when you consider the fact that Medicare participants, on the average, are generally unhealthier and need more services then other health insurance participants.
The simple fact is that the government, by its very nature, is going to cost more than the private sector doing the same thing. This is because the government does not worry about profit or service, it just exists to collect taxes.
Also, I already pointed out that the reason the private sector is not doing the things you mention is because the government made it illegal. Let is take an example where I can actually prove my point, ATC (air traffic control.)
The US is the only major country where the government has day to day control of air traffic. It also ranks last in terms of how well the ATC system responds to market changes.
U.S. trails other countries in air traffic management: IU News Room: Indiana University
Other countries have actually proven that not collecting taxes to finance the ATC works, They have proven that separating the regulation and actually running of the ATC is beneficial, and that the private sector can actually do a better job of responding to the real need.
Proof that the reason the private sector does not handle ATC is not because they cannot, but because the government will not let them. Pointing to the fact that something is not happening as proof of anything while ignoring the fact that the government makes many things it does illegal to compete with, just like they did with USPS a few years ago, makes you look like a hack.
