Treatment wasn't denied to them before the Government takeover of healthcare...and there is nothing that would indicate their car would be less if we went back to the pre Obamacare days.
You're trying to create a crisis where there is none.
Some of the justification for Obamacare was, that although they had "last resort" health care, they lacked "preventative" healthcare, that others got with health insurance.
So instead of winding up in the emergency room, they would start in doctors' offices, regular checkups, would adopt more healthy lifestyles, etc.
But soon after Obamacare became widely available it was determined they still went to the MORE COSTLY emergency rooms.
And we are in the midst of a costly and deadly explosion of opioid use. Apparently those folks failed to appear for their routine checkups, and/or failed to follow doctor's orders.
The Biggest Problem is the "Collectivization" mentality, whereby I am forced by do-gooder government edicts, to pay for massive harebrained schemes, of making drugs quasi-legal, making so-called "minor" crimes like traffic tickets, etc.
California is a laboratory classroom for the above. Ask a policeman to get the homeless out of a park. He will explain it is not against the law, to be homeless.
Tell the officer that 2/3 of homeless are addicts/alcoholics and/or mentally ill. He will explain the voters have decriminalized drugs. And have made lesser crimes mere citations.
Vagrancy is no longer a crime. Loitering is such a low level crime, the officers rarely bother.
Where as the "weaker" were once kept out of sight, they are now "mainstreamed" among us.
And do-gooders, many from the "right," would guilt trip us into believing some "collectivist" crap we ought to be compassionate, help them, etc.
