That's right, everyone has to buy something, including illegals and corporations. I heard several years ago, that a national 1% sales tax would generate more money than an income tax. Reason was, it would pick up where people work (under the table) for cash, and don't report it to avoid taxes, but do spend it. I didn't think about illegals. If corporations buy equipment and things just to write off "expenses" to avoid income tax, they would pay the tax on the stuff they bought. A national sales tax would solve a lot of problems.
