Medicare for all and single payer are not “socialized medicine.  Our politicians try to use “evil” words like “socialism” to scare misinformed conservatives about what's best for them.  An example of socialized medicine is the care delivered through the Department of Veterans Affairs, where medical professionals are government employees and the facilities are paid for by we the people. In contrast, single payer and Medicare for all are universal health insurance, not socialism.
Nobody is talking about government taking control of doctors and hospitals and nurses and everyone else. It’s about we the people creating our own insurance pool with no profit seekers skimming off the top and trying to deny healthcare. Our 250 million-strong pool of people contributing to this program would lower costs for everyone and give more money to actual medical professionals.
