The wealth disparity is the same, but the populace and circumstances are a bit different:

1. There was not a literal fascist propaganda news network brainwashing half the voter base (Fox news)
2. There wasn’t a significant population which believed any ol conspiracy tossed at them
3. His political opponents didn’t have a cult, comprised of anti-intellectuals
4. We didn’t have an enemy state attempting to influence our elections (at least, not nearly on the same level)
5. Had a serious left-leaning populist political opponent in Huey Long (before his assassination) preaching his Share the Wealth progam.

I don’t disagree that it was a hard fight for the working class to even get that much, even without those externalities
