Book excerpt: In Freer Markets within the USA, the author evaluates present tax system and other tax proposals. He suggests gradual, practical, free-market changes that reduce specialized tax breaks and level the playing field for the working person. Instead of having specialized tax breaks for nearly every type of income in which actual work is not involved, a free-market approach suggests moving toward taxing different types of income the same. The author suggests ways to make social security and Medicare more solvent, health care more affordable, the federal government more financially sound, and the economy more stable and efficient. Topics such as monetary policy, market bubbles, trade agreements, immigration, unions, employment, national debt, spending, and voting are also discussed.
