These simple changes would go a long way.
The Alliance Health Plans that were allowed would boom if natural groups (any group formed not to purchase insurance) a Credit Union, your Church, all the Churches etc in your town as a group member would be allowed to join, and with you tax free dollars, purchase a group plan throught them, as noted above would darn near cure all this madness IMHO...
Could the taxfree dollars be in the form of a write off for those the insurer verifies as covered? There’s an enforcement and public policy issue if not.
