The US GDP per capita was already around $15,000 dollars per head in 1945. Even if America flatlines from 1945 to the present, it won’t be third world.
But how do you get all the Americans into the reservations along side the nativesWest Virginia, Native American reservations...
4.. requires geologic PODS - The USA had a fair amount of mineral wealth. cheap oil and gas allowed for air conditioning in the south.
I'm surprised no-one mentioned Rumsfeldia yet.
hence the corruption and other parts of the equation.. the USA has been moderately lucky in the one thing it has done has been at least try to have some sort of a middle class .. hence why I think the pod would have to be quite early in history. The USA was founded on the idea of self determination and success, for the most part land was given away to get people to go settle places and build things. In effect you have to completely change the idea of what the USA is and was to people and at the same time make the oligarchs and the government a lot more screwed up then they were/areThere are lots of third world countries with plenty of mineral wealth, and don't benefit from it internally due to massive levels of corruption.
McCarthy is never discredited and becomes an anti-Communist crusader with support in both parties. During the 1950s, the Smith Act is used against anyone to the left of Richard Nixon, and hundreds of thousands of suspected Communists are jailed. By 1960, the Democrats divide over civil rights issues, nominating a strongly anti-communist and pro-segregation candidate (Allan Shivers perhaps, or someone similar). He wins, and the US takes a hard and permanent turn to the right as the result of massive voter suppression.
totally farfetched I know
There's a lot of that in this post.
A USA gone that far off the rails in the 1950s would have started WWIII with the Soviets by 1960
Make US political history resemble Argentine. No FDR, US undergoes a decline similar to Argentina post-1945.
Add some racial strife/Drama to the mix to generate more confusion.
2019 US is at OTL Argentine levels.
UN and peacekeepers exist in 19th century.
Spend some time in third world countries.
