It's called a value-added tax, or VAT, and it's been used for decades to pay the bills and sustain the immense growth of governments around the world, from France to Mexico to Australia. Created in 1954 by a French economist, the VAT is the most potent, efficient machine for revenue generation yet invented.
And if there's one thing the U.S. government needs as the federal budget balloons, it's a ton of new revenue. "The bottom line is that the income tax cannot support the level of spending that's projected, something other countries faced years ago," said Roberton Williams of the Tax Policy Center, a non-partisan research institute. Today the VAT raises almost half of the total government revenue in France, and a similar share in most of the developed world.
The VAT is essentially a sales tax, except that it's charged at each stage in the development of a product instead of at the moment when the product is sold.
