Informal economy
Informal economy is defined as working without an employment contract? That describes every employment-at-will state and company in the U.S.A. This is just another reason I worked as a US street vendor for a few years. The IRS will bill you for self-employment Social Security tax if you file a return so you do get credited for that work time. Since our economy rapidly is degrading into a two-tier Third World model, secure employment is disappearing, and pay declining, Americans may as well use the street model/home-based business model to be loyal to our bottom lines. In America, free enterprise is regulated most at the bottom of the pyramid-those at the top purchase exemptions or the regulators themselves. We need to resist excessive regulation of small startups or zoning exclusions of home-based enterprise.
