Why Can't We Do This?

BRATISLAVA, SLOVAKIA – A few years ago, Martin Bruncko studied the flat tax at Harvard University. Today, the 28-year-old is flying to European cities to promote the idea, which he made a reality in his native Slovakia.

"In theory it was interesting, but we never thought we could do it in practice," says Mr. Bruncko, recalling class discussions at the Kennedy School of Government. "So it was fun to see that you actually can do it."

What flat-tax advocates like Steve Forbes and the Hoover Institution's Alvin Rabushka have been pushing in the United States for decades, Bruncko and a team of Western-educated wunderkinds in this country of 5 million achieved in one year.

Last January, Slovakia became the sixth Eastern European country to adopt a flat tax, which means all income-earners pay the same rate. Since then, Romania and Georgia have followed suit, creating a global proving ground for the concept. In the process, flat-taxers have moved Eastern Europe from a Communist backwater to an investment spring - pressuring its higher-taxed Western neighbors to adapt to the new environment.
