I can easily say, "having private insurance in American, frankly, its not that good."

Proposals I've previously heard: Medicare for All, Medicare for Children, Medicare reduced age, a public-private option, improved transparency in costs (i.e. a menu), pin costs to Medicare + X%, allow insurance companies to operate across state lines, better subsidize preventative medicine, force clinicians to be able to speak to costs (similar to dentists/chiropractic/optometrists/dermatologist), reduce patent length or add a maximum return on investment to patents (e.g. 10x or 100x R&D costs?), etc.

Literally any of these would be an improvement. Please tell all of your representatives (regardless of politics) to fucking execute on any of them so things improve at least a bit from where it is now.
