This already happened. When deindustrialization first hit in the US it devastated the black community. The result? A litany of pundits decrying Black criminality, bad family structures, cultural pathologies. It's no coincidence that The Bell Curve came out around then.

A decade or two later, all of sudden the same phenomena are happening in working class white communities. Drug addiction, family dissolution, abject poverty. So clearly the people of the US finally realized that what was happening was due primarily to material concerns, and that people need to be able to earn a living in order to live. Right?

No. Instead we got right wing populism, scapegoating of immigrants, further concentration of wealth, and no end in sight.

With those past examples the majority of people thought "It's not my problem, I won't be affected", and they were mostly right. With an automation wave of the scale needed to get to effectively no jobs, that's just not the case. They will see that it is indeed coming for them, their friends, and family. They will act accordingly. Altruism not required, just self interest.
