They don't need to create big scale economic opportunity, but what they can do (since we are talking about people living pay-check to pay-check) is create programs that either prevent people from falling off a cliff, or programs that at least soften the fall at the bottom. This is the Nordic-model of social capitalism that
@Humphrey Bogart is espousing. Programs like free (meaning tax paid) higher education, free health are, free eldercare, free day care, maybe even UBI! And before you or anyone else says it, the Republican/conservative talking point that "welfare makes people lazy" has been repeatedly debunked; people want to work and have meaningful lives and careers.
