Long is an interesting example, since he definitely did strongman Louisiana politics, but he did seem to have the working class interests at heart, where as Trump only pretends to. We didn't get to see what he would do long term, but its been argued that his presidential run, and more specifically his 'share our wealth' program forced Roosevelt even farther left in his policy.
Share the wealth proposed to put into federal law a wealth cap of 5 million for every American, with the excess used to fund what amounts to a universal basic income back in the 1930's, and didn't discriminate against minorities. It also advocated for free education, free healthcare, and a 30-hour work week.
From all the information I've seen, including the excellent Ken Burns documentary, the poor and working class of Louisiana loved Huey for legitimate reasons, while the rich and politically corrupt, who were targeted by him, absolutely hated his guts.
That sounds similar to this quote:
"It is practically impossible to teach good programming to students that have had a prior exposure to BASIC: as potential programmers they are mentally mutilated beyond hope of regeneration." — Edsger Dijkstra, 1975
But there's been a good deal of programmers who have said that BASIC, and its ease of use and seeing almost instant results is extremely useful to not turn people off learning to code to begin with. Python is functionally the new BASIC in that regard, and while the language itself may not teach you to become an expert programmer, it may have gotten more people in the door than otherwise would have.
But that's just my 2 cents.
