Politicians like to talk about the income tax when they talk about overtaxing the rich, but the income tax is just one part of the total tax system. There are sales taxes, Medicare taxes, social security taxes, unemployment taxes, gasoline taxes, excise taxes - and when you add up all of those taxes [many of which are quite regressive], and then you look at how they affect the rich and the poor, you essentially end up with a system in which the best off 20 percent of Americans pay one percentage point more of their income than the worst off 20 percent of Americans.

One of the tax systems in the US is for wage earners. The government takes money from them out of each paycheck - so it knows how much they make, and those workers can't cheat to any significant degree. But the other tax system is for capital. Those with capital get to tell the government what they want to tell. They may get audited, but if their tax returns are of any size the government doesn't have enough of the smart auditors to figure out what's really going on. And there are the rules that allow you to do things like take in money today and pay taxes on it thirty years from now.

You, as a wage earner have to pay your taxes every year on your income for that year. So if you have a one-time windfall that makes you a lot money you could end up in the top tax bracket. But if you're a corporation you are allowed to reach forward with deferrals for years. Over a 45 to 50 year period, you can balance out the winning years and the losing years in such a way that you pay very little tax, especially considering the time-value of the money.

Senior executives can, after a fashion, get a portion of their pay tax-free. You defer part of your income and not have to pay taxes on it, and then when you retire you have the company buy a life insurance policy on you using that money. The company can deduct that money because it is a business expense, and the money will get paid out to your children or grandchildren when you die, so you have effectively given them your money and it's never been taxed.

What the Trump tax plan is a plan to give tiny little tax cuts to most Americans, raise taxes on perhaps one in five families and shower benefits on people who earn millions of dollars a year. And this fits with a fundamental principle the Republicans have been pursuing for a long time. The rich aren't investing and creating jobs, because they don't have nearly enough money, and so we need to get them money. And the way the Republicans want to get it to them is tax cuts first, and then to take away help for children, the disabled, the elderly and the poor.

When you say the tax system benefits the rich, there are a lot of people who respond, "That can't be true, look at the rate of tax. The people who are rich pay a higher rate than you or I." Well, yeah, but if you don't have to pay taxes on a lot of your income, then your real tax rate is a lot lower. And if you're allowed to pay your taxes thirty years from now instead of today then you're a lot better off. People need to have a sophisticated understanding of how the system works to appreciate that the posted tax rate really has very little to do with the taxes people pay.
