Wrong, three or four illegals will take care of 200 yards a month while another 3 or 4 will do another 200. The boss, the white guy in the big red Chevy that pulls the trailer will drop the illegals off in the neighborhood. He will charge 25 to 50 per lawn making him somewhere in the range of 15,000 per month. He will then pay his guys maybe 500 a week tax free (contract labor). That leaves him with 11-12000 for his family.
Of course these illegals have no loyalty to America and send much of the 500 home so their family can live high in Mexico.
Let me also take on this "harder workers" myth. True some work hard and some don't. I worked with an American guy who was Hispanic and as we drove by the guys standing on the corner waiting for a contractor to show up he called them "a bunch of lazy bitches". I was shocked because I was under the impression all Mexicans were hard workers, until I worked around them and found out some were and some were not, surprise, just like everybody else.
When I got out of the Army I went to Alaska to work on a crab boat. In Alaska you can work on a boat and make a years wage in about 3 months. You work for 15 to 18 hours a day and then go home and live off it. That must mean all fishermen are incredible workers.
I guess you would be happier if this guy was doing a "less' evil living to you than running a lawn care business, such as operating a crack house.
