Sounds great, but the kicker similar to the Affordable Care Act is if everyone signs on.  Guess what alot didn't because they felt that they didn't need it or two that the penatlies were way cheaper than signing up through the marketplace.  Now if i'm reading this right Bernie's Medicare for All Bill 2017 will go through a four year phase in requirement (great idea phasing this in) but... Will the masses do the same thing and 'opt out'?  Since i believe this is betting on the individual vs the masses to lower the medicare costs it theoretically could follow through better.  Just trying to determine if a certain part of the population 'young adults' and 'wealthier citizens' will keep out based on well youth and wanting a specific 'in coverage doctor'.  So I believe there may be three to four groups if not all going to squirm at this.  I still think this is an interesting option but just caution on not repeating what happened to ACA.
