Landscaping and commercial lawn service is just part of our biz ( we only do a few residential lawns because we have to charge tree service price, we do commercial lawns ) , and most of our biz is tree service with a bucket truck with wench , 2 hi-lifts.dozens of gasoline chain saws including pole saws of various lengths. Landscaping and lawn service are more often combined but usually not with a full tree service biz, actually most biz in Texas are either lawn service , landscaping, or tree service, not all three. And I don't know about other areas in Texas but our area is NOT dominated by illegal or even legal immigrants doing the work, like I said in our area border patrol is very active and effective and fines are enforced quite diligently and the prejudices against immigrants are rather intense which is apparantly a very strong deterrent. I expect it is more like you are describing in large metropolitan areas and the loss of good paying jobs has more to do with an increase in independent contractors than anything else. Well over 30% of all jobs in Texas are minimum wage jobs that do NOT provide health insurance, etc. universal healthcare would be the best solution, I would never agree to anything that would guarantee income to lazy good for nothing slobs, druggies or alcoholics, etc. that just don't want to work, I believe working for a living and the struggle to attain success builds character, strength, in many cases empathy, and all the qualities that make a person a better person. I find the people that have had it too easy in life born with a silver spoon, or just good at scamming the system and living off of the work of others are usually lacking in empathy and most of the qualities that I think are necessary to ensure future generations do not become weak, pathetic, greedy, selfish takers who think the world owes them, and are encapable of giving, contributing, sharing, etc. etc. .
