I do like a nation sales tax.We need to capture some tax money from the people that work for cash.Their is a huge amount of unreported income that we would recover some tax from.Other then doing nothing about it and the rest of us paying for them.Why should someone working cleaning houses or any service work that are being paid in cash get away with paying nothing.Just think of all the tips you have given people most of that is never taxed,I have known bartenders that made 200 a day in tips and most of it unreported.A sales tax is the only way we will get something from this unreported income.
