Many of the current crop "populists" don't really have a program that would actually help the people whose support they've gained through emotional appeals. They're mainly just trying to harness dissatisfaction with the current order to fuel personal ambition.

IIRC, the original populists actually opposed the gold standard, when it was still actually a thing, and supported silver because it was more inflationary. They understood deflationary money helps the people who already have money, and inflationary money helps the people who are in debt to them.
