Here is a Fresh Air interview with T.R. Reid explaining how great the VAT is.

This is the most important innovation in taxation in the last 60 years. This is a tax that’s like a sales tax on steroids. It’s a tax – our sales tax is called a retail sales tax. The tax is only collected when the retailer sells you the book. But on a value-added tax, a tax is collected when the paper mill sells the paper to the publisher and when a publisher buys ink from an ink company and then the publisher sells it to a wholesaler and a wholesaler sells it to a distributor, distributor to the bookstore and the bookstore to you.

That tax is collected at every level, and every time you pay the tax to the other guy, you report it to the government to get a credit for the tax you paid which means every penny of tax that’s paid is reported to the government. So the VAT turns out to be a very easy tax for government to collect and a very hard tax for taxpayers to avoid. And so if you put in a value-added tax, they’re very steady collections, and it’s hard to cheat on.

And you could use that money to reduce the rate of the corporate or the personal income tax. So 176 countries have adopted this innovation. It’s a great idea. The only countries that don’t have it are a bunch of countries so poor they have no taxes and the United States of America. So I say in my book in taxation, Americans are still banging out letters on a typewriter and dropping them in a mailbox, and everybody else is texting and using Instagram.

So let’s do it. There are actually some signs the Trump administration might consider it. But instead of eliminating income tax, they may be thinking of going after the Social Security payroll tax.
