The difference is that this affects his voters' (the ones with any money) place in the hierarchy. If their retirement accounts zero out, they're no different from the poor people they consider themselves above and made so many choices to separate themselves from. If they introspect a little bit, they might even say "then what have I been working so hard all this time for?"
The dems become the rational alternative. These Trump voters can hold their nose and vote for a little less brutality on the trans folks and a little more DEI lip service as long as they stabilize the market.
Meanwhile ofc the dems are likely to keep 80% of the immigrant deportation policies, tax cuts for the rich, etc.
