I'm not a big fan of Trump, but if he actually delivers on this campaign promise (even if it's just scrawling his signature on the bill and then taking all the credit in speeches) that will be a good thing for me and most employed people on slashdot.
There's no doubt that he can push through a number of short-term fixes that make him look good, and maybe it will create more jobs for Americans, at least in the beginning; but isn't this what was criticised severely during the early years of financial crisis - and still is: that there were strong incentives for the executives to make a quick buck and then cut your losses and run, leaving the fall-out to those left behind?
Just to take an example: Trump wants to abandon everything that has been done to protect the environment - he wants to introduce more coal burning, he wants to scrap the Paris agreement and drill for oil in the Arctic etc. Apart from the damage this will cause to America's environment and the health of Americans, down the line, it will also mean that Europe, China and India will continue to get ahead of America when it comes to renewable energy technology, environmental protection etc, and they will build up sustainable industries on top of this, which will provide sustainable jobs etc, while America in years to come will be forced to go and buy this from outside, when a future government finally decides to come to their senses.
Is there any way this is a bad thing? H1B was supposed to be for bringing in essential foreign talent. If a company isn't willing to pay $100k per year plus the various expenses, whoever they are bringing it must not have been all that talented.
I don't know - but I suspect it is not as simple as you make it sound. In many countries in Europe - especially in Scandinavia - there has traditionally been rather stiff rules about minimum wages, and it as meant that the business climate simply wasn't as attractive as in many other countries. The was one of the many contributing factors that pushed up income taxes and foreign borrowing for many years, and the attempts at getting the rules loosened up have caused social unrest, strikes etc. I'm not against minimum wages, but you have to have a well thought out plan so you are prepared to tackle the consequences. And I have seen no indication that Trump has a plan - his stance on climate change consists mostly of ignoring science and walking away from international agreements; it's a bit like keeping warm by pissing yourself - it works, but only briefly, and then you have a more pressing problem to deal with.
