A defazio financial transaction tax (FTT) is a tax on the buying and selling of stocks, bonds, and other financial products. It's named after U.S. Representative Peter Defazio, who proposed the tax in 2010 to help pay for programs like Social Security, Medicare, and education. The idea is that by charging a small fee on every financial transaction, companies selling these products would make less money, encouraging them to invest in more productive activities, like infrastructure and job creation. This, in turn, would help create a healthier economy. People who buy and sell these products would be charged a small fee, which would add to the cost of those products and reduce the amount of money they make. This would hopefully help reduce speculation and provide more money for necessary programs.
