By many metrics, the US economy is humming along. The jobs market is robust; consumers are spending again; and inflation has eased to a three-year low.
Economy isn't everything. People need more like believing in the future, a sense of community, etc. A lot of things incompatible with neoliberalism that the dems embraced in the 80s.
This push them in the arms of the extrem right. Don't take me wrong. Extrem right isn't better, it's worse. But they are the last untried thing and extrem right as a rhetoric that hide the reality.
The dems have to change in deep to address the real issues like inequality, housing, belonging to a group, etc. It's placing the human in the center.
