Corporations do not hoard profits if they did they would have no investors willing to buy their stocks.
Decreasing the tax burden on profits will mean not only will those costs not be passed on to the consumer but more money will eventually end up in the hands of individuals where it will then be taxed
Corporations do hoard profits. They use some of them to buy back shares to artificially support share prices and to pay dividends to shareholders.
US corporations are sitting on hundreds of billions of dollars of hoarded cash right now. They could use those funds to invest in their businesses, but they won't because there's no demand present to justify that. And that's because too many people in this country can't afford to buy the products they produce.
If they were to spend some of that cash by raising employee compensation, put that money to work into the economy by putting into their employees' paychecks, then demand for their goods will grow and they can use more of that cash to expand their enterprises to meet that demand
Everybody wins.
Decrease the corporate tax, or any tax, simply accelerates the growth of our debt. Cutting taxes doesn't reduce spending because they are no longer related (not since Ronald Reagan legitimized the concept of cutting taxes and then borrowing massive amounts to pay for the cost of government).
And we know that we can't cut spending because since the dawn of time we never have, no matter who controlled congress, who was in the White House, or what party made the most noise about cutting spending. It has never been done because it cannot be done. We spend it one way when one party is in power and we spend it a different way when the other party is in power and the only thing they both do is borrow, borrow, borrow to pay for it because our tax revenue is insufficient to pay for what we spend.
We know that it's impossible to cut spending significantly or for any significant period, so cutting taxes has but one effect - accelerate the growth of our already humongous debt.
You want even more debt? Reduce corporate taxes for the 40% of corporations who pay corporate taxes (the other 60% are structured as pass-through corporations and don't pay corporate tax).
Concerned about the debt? Then raise taxes, starting with those at the top who have benefited the most from thirty-plus years of unaffordably low tax rates. It's time to share some of those politically motivated gifts with the rest of the country for a change. We need the revenue more than they do.
We always have.
