anyone that can correct the income distribution problem that began to occur 1970's (almost all real income growth to corporate leaders only, a very small share of the growth to people doing the work in corporations) would be a worthwhile candidate....read up on the Lewis Powell memo to see the game plan corporate American / big business has followed since 1971 to get laws/court decisions/public opinion to favor corporate economic interests over those of ordinary citizens.
If Biden/Warren/Trump can counteract the growing income gap, yes indeed they are good candidates imho.....I don't care how they do it..raising corporate taxes, raising tariffs, guaranteed income, or limiting immigration to drive up wages....whatever works
