They're mostly Brazilians. They come up from S. America for six months at a time, do landscaping, painting, etc., for slave wages under the table and take jobs away from Americans that make their living on these summer labor jobs, and then go back home and live with their families off the money until the next season. I know this for two reasons - my house cleaner is Brazilian but is an American citizen, and she lives in a Brazilian community so knows the workings, and Mr. PFL owns a painting company, has lost a lot of work, and doesn't hire anyone but former union painters that actually know HOW to paint.
