I, for one, would love to see more nurses, doctors, elder care workers. We should want more of these workers, not less. One could argue that AMA needs to be forced to increase the number of workers in these fields and reduce occupational liability for healthcare workers. But even that will fall short of what is required in greying America today. If you want real world evidence of this, look at Canada which is frantically trying to get immigrants because their elderly population has no one to take care of them.
Making people reproduce will take a wholesale change in the American way of life. This would include wholesale changes in food, healthcare, health insurance, housing, inequality and a general well-being of humanity. One party in our country is actively attempting to reduce liberties (this party is red in color if this is not obvious), which makes living in this country a precarious position.
As an older child-free millennial, I am living the scenario described in the article. I can assure you that my life path hasn't been easy for the first 35 years. I have zero interest in making my life even more difficult for the remaining 35, for the sake of society.
Make healthcare easy, then we'll talk. Until then, I thank immigrants in America.
