It's just the natural course that free enterprise takes. Competition forces businesses to always be looking at ways to be more efficient, to more with less. I've been in manufacturing my entire adult life and have attended a lot of manufacturing related trade shows and whenever looking at new machinery or processes the #1 selling point is always, this will save time and labor. I've yet to encounter a company that touts their machine or process is labor intensive and you will need to hire more people........
Not sure how it is now, but 15 years ago if you gassed your car in Japan it took 3 to 6 attendants to do so: gas, oil, windows, etc. Japan prided itself on a very low unemployment even in bad times.
In Oregon, you're not allowed to pump your own gas. It was supposed to promote employment, but at so many stations, it's just the one employee that does everything.
I agree that foreigners are not taking "our" jobs. First, no one is entitled to a job. Second, technology has always changed the job market. Car production put horse buggy manufacturers out of work and robots will be replacing more and more jobs. Third, history has shown that more jobs always appear and the same will happen with robots. You have to ask yourself if your job might be replaced by robots and, if so, start planning now.
