ezbee:Farming is the largest user of illegal immigrants.
Houses get built by illegals, Trumps Golf courses employed and probably still do illegals.
All kinds of day labor like lawns and gardens etc.
They are cheap, easy to hire, easy to fire, don't talk back.
Yup, a good chunk of the unskilled and semi-skilled labour in the US is illegals because the US economy requires millions of labourers to do dangerous, unpleasant, or uneconomical work that can't be filled by locals. Illegals are completely ingrained into US culture, it's just accepted that if you want some sort of labour work done like gardening, debris removal, etc, you get in a bunch of hispanic gentlemen via some informal labour exchange and pay them cash, no questions asked.
They also help the US economy another way, for the ones who work on the books they pay large sums into income tax and Social Security through paycheck deductions via false SSNs but are excluded from receiving the benefits of most welfare programs since they're illegals. So the illegals are heavily subsidising the legals.
This is why apart from racist boneheads and people making political capital from it, no-one actually wants to get rid of the illegals, it'd be really bad for business.
