Rank choice voting would help more than any other single change...
Problems are far worse and nobody can fix it-- Americans blame politicians but will consistently vote to screw themselves. Americans deserve what they blame others for which is why we are doomed.
Economics: non-productive jobs like education/medicine rise in cost as productivity benefits most jobs which also reduces labor demand in those and lowers pay; plus you've got outsourcing too - say you buy American but actually you don't. Housing also is not getting productive (and when it does, tons of those jobs are gone) and lowering housing costs devalues the "investment" of the largest voting block who will not allow enough policy changes. Green costs more upfront and that is too much; it has to be better and cheaper (not green; very few will lift a finger for ethics, they will do it for their own personal gain only.) Selfishness is way too popular and marketing exploits that from every angle for generations now; best you get is lip service, bumper sticker, "A Scause for Applause", or rounding a bill up as a "donation" (which is a tax break for the business, not the customer who pays for it,) or a twisted smugness for being an anti-do-gooder (couched in tribalism which even trumps Christianity.)
Biden on abortion: ridiculous liberals can always be counted on to harm themselves and are quite similar to fanatics on the other side. 1 side has a media machine that is good at pushing such buttons and reaching people while the other side has basically nothing and whatever they have is not an organized propaganda machine designed to be an echo chamber.
