What happens to America if Republicans capture the working class demographic?

In the hypothetical scenario where Biden/Harris win the election, and we enter the inevitable economic collapse (that will happen no matter who wins in November), what happens to the working-class electorate? Are we going to see the blame placed on the failures of Neoliberal policy and the Democratic party?

Will right-wing populism permanently capture the working-class demographic as the DNC focuses on virtue-signaling and identity politics? Could we see an extreme, right-wing, nationalist leader rise up with a right-wing populist message that addresses the economic concerns of the working class? Someone more competent, articulate, charismatic, and intelligent than Trump? What would that America look like?
