The USSR existed back then and the USSR was doing very well at the time up until 1975,
right after the petrodollar scheme was made and SWIFT was introduced.
Because of that, the US had strong labour unions.
Socialism was popular back then,
although the US was also able to propagandize that it was explicitly not doing that in the slightest.

Nowadays, the US will have to fight again against capitalism.
And capitalists are warring to survive, not just abroad,
but at home as well.
Their ideology currently is that capitalism has won,
communism has lost and therefore any concessions to the left
will no longer have to be made.

And US Social democracy isn't coming from the top this time,
when FDR decided to take a turn for the left and continued going left,
up until Jimmy Carter was replaced by Ronald Reagen.

This time it's coming from Zohran Mamdani
and this time it looks like it's taking the form of democratic socialism,
a step more to the left than social democracy.

With better job availibility, your father would have had a much easier time
maintaining a good income and thus a family.
You however, would have a trade-off.
Better job security, but little to no knowledge of your sexuality.
Also terrible medical practises, barbaric in some fields.
