Finally, for now, let's look at this idea that a national sales tax would somehow be unfair.
Take two people who are the same in every economic way but one. They intend to spend 70% of their income and save 30%. The only difference is X earns twice as much as Y.
Well, he may earn twice as much, but because they spend the same share of their income, he also spends twice as much. That means that with a national sales tax he pays twice as much tax. Is this wrong? I don't see why.
Both men have a stake in protecting their property from invaders and criminals and so on, but because X has bought twice as much as Y, he has twice as much stake, twice as much to lose. So he should pay twice as much tax - not 1.5 times as much or 3 times as much or 30 times as much. Twice as much. Fair is fair.
Kazan says that in fact, things aren't really like this. The rich spend a lower proportion of their income than the poor. Maybe so. But if they are only spending, say, 20% of their income in a particular year, they are only getting the benefits of their money to that amount. The important figure therefore is not how much they earn but how much they spend. If X is only spending 10% more than Y even if he earns twice as much, then he must be living in a very similar house, must eat very similar food and enjoy very similar luxuries. Sure, he'll be a bit better off each year in terms of what he buys - about 10% better off. Then that's how much extra tax he should pay! With a national savings tax he would.
You might say that X has lots of savings he can spend later on, and those benefits should be taken into account, too, because they are worth a lot more than 10%. But they will be! With a national savings tax, as soon as he spends those savings in ten or thirty years time, he will be paying the sales tax on whatever he buys. The only difference is he is paying less now and more later.
If he never takes his savings out of the bank, that's fine too: there is nothing anti-social about this. It simply means that all his life, because of his savings, banks have had more money to loan out to the rest of us, creating jobs and wealth all over the economy. The money is not withdrawn from use by its being saved and then loaned out by a bank. It is simply transferred to the current use of people who borrow from banks to invest, to start a company or to take out a mortgage.
Whichever way you slice it, a national sales tax is fair. If someone spends half as much as you, he is only getting half the benefits you do, so he pays half as much tax. If he spends twice as much as you, he will get twice the benefits you do, and so will pay twice as much tax. If he saves now and spends later, he'll not pay that much tax now, but he'll pay more tax later on. If he saves now and doesn't get around to spending later, he'll not get more benefits now or later, and he won't be charged extra taxes now or later either.
Unfair? Don't make me laugh.
