Just a thought -but I am told that many large corporations are sitting on mounds of cash -

and I am also aware that many large corporations not only don't pay income axes, but actually get rebates from the United States government.

So - how much of that money these corporations are sitting on is money from our income taxes?

Edit: the worst part - often a cash rich corporation goes out and buys another company rather than investing the money in new jobs. Given that many buy-outs result in golden parachutes for the execs and shuttered work places for everyone else, we're paying taxes to put ourselves out of work!

1. All of it, indirectly.

Since bills have to be paid, if they don't pay their taxes then we have to pay more.

The rich get richer on the backs of the middle class, same with the corporations.

2. Transfer pricing.

Google that. It's one way companies don't pay money on taxes. Big multinationals that is.
Lots of other very weird and advanced tricks as well. The IRS does try to clamp down on transfer pricing tricks, but it's very hard. A big cat and mouse game.
