Yin and Yang....If the economy pushes too far right (e.g. making the richest 3% richer), it will inevitably push more people further left in the economy.
Many of the "centrist" Democrats are shareholders, so their economic interests are aligned with the far right. Who cares if their social ideology leans left? It is the economy that really counts.
Democrats need to do a clear-out of their lobbyist politicians with some new meat. If a Muslim not even born in America can win New York, so can people born in America- with ease. They can take the independent vote with ease.
The Big Tech Oligarchs, like Bill Gates, are often on the left wing on social issues, but far right on economic issues (e.g. less competition and monopolies to boost shareholder value).
