I read a story a few years ago about a man who cut hair at the local flea market, which is a very large market. He made an incredible amount of money and I imagine it was all under the table.
It seems that is the only way young, ambitious people who dont have an Ivy League degree can make it these days.
How I wish the know-it-alls in Washington would just get out of their way.
Read about a guy who ran a parking lot. Sold tickets out of his little shack for about 20 years. One day, he was gone. Turned out, it was a city parking lot and nobody was running it at all ever. Guy made a mint.
I dont know what state this is in, but where I live he would not be able to do this without a cosmetology license, business license, and I believe a health department inspection relating to hygiene and equipment sterilization. You could get away with it at your house but not in a public place.
