Americans are discovering that giving universal healthcare access to everyone means those who already had access, now have to wait longer to make room for everyone else. That's how it works.
No they aren't. Americans are finding out that when you abuse medical workers by calling them "essential workers" who have to continue working during a pandemic while hundreds of thousands of patients berate you for saying things like "you should get vaccinated" or "don't eat an anti-parasite medication for horses" and overwork them and pay them shit, they quit in droves.
They are then finding out that for profit businesses have no interest in re-hiring all the workers they had before the pandemic, because they didn't lose as much business as they saved money in salary, so everyone is just running a skeleton crew that they overwork.
Meanwhile the data I find for emergency room visits are that there's barely been any increase in percentage of the population that visited an emergency room since 1997.
Companies are spending less on services and letting us just suffer because we don't have better options and YET AGAIN dumb Americans for some reason blame the government for completely independent companies making self serving choices?!
