Some here may want to talk to the farmers in various parts of the country to see how immigration laws are affecting them.
Americans in general may want to also consider the overall increase in the cost of goods and services when the illegals (who will work for cheap because an hourly wage in America is a daily wage where they came from). A more expensive salad and vegetables are not going to affect the likes of billionaires like Donald Trump, but for his supporters that are not billionaires, or even millionaires, or not even considered in the wealthy class, food is going to cost more and so are their hotel rooms, their lawn mowing, gardening and a whole lot of other things.
As for the wealthy Trump supporters, they are likely going to find a ready supply of foreigners in American to pay under the table for maid service (or to boff on the side like Arnold S. did) au pair and other services. Some of my still republican (of the neo type) relatives are always giving me tips on how to hire and pay people under the table (I just roll my eyes).
Institute on Taxation and Economic Policy Study
"The Institute on Taxation and Economic Policy released a report in February 2016, stating that 11 million illegal immigrants in the United States are paying annually an estimated amount of $11.64 billion in state and local taxes, "on average an estimated 8 percent of their incomes."
Social Security subsidization
"Illegal immigrants pay social security payroll taxes but are not eligible for benefits. During 2006, Standard & Poor's analysts wrote: "Each year, for example, the U.S. Social Security Administration maintains roughly $6 billion to $7 billion of Social Security contributions in an "earnings suspense file"—an account for W-2 tax forms that cannot be matched to the correct Social Security number. The vast majority of these numbers are attributable to illegal workers who will never claim their benefits. For 2010, the Social Security Administration estimated that illegal immigrants and their employers paid $13 billion in social security (OASDI) payroll taxes".
Yes, technically what both employers and people here illegally are doing is illegal and should be stopped, but speeding and running stop signs are illegal too, but few, if any are calling for a crackdown on traffic violations simply because they are illegal and need to be enforced. I have also always felt the pulse of American attitude and consideration of others, can be felt by driving on America's highways. We've definitely become a greedier, more selfish and self-centered society, by that standard, as well as simple awareness of other people in the world aside from themselves. Walk along a busy sidewalk or in a mall and groups of people will take up the entire width of a sidewalk without the slightest awareness or care there are people coming toward them or behind them that would like to get by. I have to say excuse me to get by when they are walking towards me and looking right at me, but not allowing space for anyone to pass and I see people going into the street to get by them. While there have always been selfish and inconsiderate people, there seems to be a proliferation of them now and perhaps that has something to do with Trump being in the White House, now. Perhaps not a big deal on individual levels, but collectively our double standards become our identity and we lose credibility when we won't walk our talk or the walk what we try to tell others they should do.
To me, Trump is so full of himself he charges into ventures he has not thought much about in terms of negatives, only about how he sees himself profiting. When they don't work out, he still has his millions, so while he "feels it" literally mathematically, his luxurious lifestyle is little changed, when he can sell a yacht or two, a home or two, but still live high off the hog. He can't relate to people on the edge who suffer greatly even with a minor negative change in their lives.
