How about the people known as "the Travelers", who are some sort of Celtic Gypsies and live by traveling about and bilking others with bad home improvements, 'boojum' scams, incompetent auto dent repair and such? They (as well as some Romany Gypsies) believe that they should pass this criminal lifestyle on to their children.
=============================
That is a bit of a biased account of the Travellers and the Roma. It sounds like something The Sun might print.
In fairness though, it is a good question. Where does education of children stop becoming a priority for society and the sole domain for individuals? This is a serious question (among others) Britain faces with the Travellers and Roma.
=====================================================
I see you have not had any of these clowns try to bilk YOU. I have, not that they got away with anything.
I did not say that all Romany and all Travelers, or even most, were scammers and thieves. I said that there are some that are, and they are famous for particular sorts of scams, at which they excell.
A friend of mine from long ago was a Romany named Pinto who had left the Romany way of life and had married a nice Norwegian girl and settled down in Aberdeen, Washington. He was far less charitable to the Roma than I, since they had bilked his father out of his life savings and him as well of a young fortune prior to that. The most likely target of a Roma scam is another Roma, he said, since there are no Roma cops to rat them out, or at least weren't back in hois part of the country (near SF CA) in the 1950's.
The Travelers specialize in home improvement thievery. There were dozens of them cruising about after Hurricanes David and Wilma, offering to do cheap roof repairs and then skipping town. The Romanys tend to come down here when they get evicted in NJ and NJ (or can't get their homes heated, at least) and specialize in ad hoc dent repair. It would be unwise to hire most of them,. because they are illiterate and cannot actually read the label on the Bondo about how much hardener to add to the Bondo. They tend to fill the dent with several inches of the stuff, take their payment, and leave, with the blob still on the fender, promising to sand it down tomorrow. They tend to never return.
