> The US was built with basically just a few kinds of people in charge: farmers, lawyers, businessmen, and military officers. It was already wealthy before there were any Ivy League professors doing anything.
The Ivy League wasn't the "Ivy League" back then - just a bunch of fledgling colleges without much of a reputation. America was a different country. Smart, ambitious people went into planting, trading, or soldiering. What things were like 200+ years ago has no bearing on how they should be today.
> Marx was a PhD and a professor and his political philosophy was the basis for several quite unsuccessful efforts at governance.
One academic's theories led to some failed governments, therefore academics are bad at country-building? Marx wasn't even in charge of any of those countries. Other people (such as Lenin, a lawyer, and Trotsky, born to a farmer) read his work, went "this shit sounds dope", and tragedy ensued.
I can point you to any number of countries run by "farmers, lawyers, businessmen, and military officers" that weren't as successful as the US. As I already mentioned, Lenin was a lawyer. So was Fidel Castro. I hope I don't need to go through a list various military dictators.
> But I want a farmer actually running the country.
I want smart people with good ideas, integrity, and communication skills running the country. You can find people like that in every field. I couldn't care less what their background is.
The US succeeded (in part) because the early leadership was of incredibly high caliber and integrity. George Washington stepped down voluntarily from the presidency after two terms. It seems normal to us but it was unthinkable back then. Everyone just assumed he'd stay in charge until he died.
