While I understand the concept of "illegal immigrants" breaking the law by just being here, we really need to look at things from a big picture.
I have a very good friend (Trump voter/supporter), she runs/owns a very high end landscaping business in the River Oaks, Memorial area of Houston. She normally has 3 FT crews, each generally working on $100k landscaping projects. She is down to 2 crews, she cannot find workers because they are scared to work. She is literally losing over $600k in annual revenue because no one else will work in the Summer heat planting and cleaning flower beds. She is upset because her crews are not criminals, thugs, rapists, they are hard workers who do the work that NO ONE else will do. She is upset with the administration because it was her understanding that only the "worst of the worst" were going to be targeted. Not her work crews.
A good friend in construction can't find framers, hence slowing down his home building business.
Another friend has a grass farm, he sells over $3 million in sod to the Houston market. He can't find help to keep up with demand and has trucks and trailers sitting waiting for grass pallets to be loaded and shipped. No one wants to work in the sun loading sod onto trailers.
I have looked into the H2-B visa for an individual that is currently here "illegally" the process for the employer is tedious. The requirements on the business owner to get H2-B visa workers is cumbersome, with very stringent requirements that small businesses likely can't afford.
I'd just like folks to look at things big picture wise. Not all "illegals" are terrible people. They pay sales tax, gasoline taxes, rents, etc. and do help the economy by keeping small businesses going.
