I know I've said this a million times (literally, Biden-style), but the solutions to the economic misery in this country and elsewhere are very simple. And I don't just mean the wee shortage of aggregate demand. Make our lives easier. Let younger people at least buy into Medicare. Scrap the 401K system and put the money saved (as in tax expenditures which benefit wealthier people) into Social Security benefits. End means- and asset-testing of everything. Make most 'benefits' universal. Think wealthy people shouldn't get benefits because they don't need them? Fine, just tax them more. Provide universal free pre-K.
It doesn't have to be so complicated all the time.
