if USSR was still around than US will be even more bad situation not because of USSR competition but those cultural and demographic trends from 1960s and without benefit of intellect of East Europeans that propel the tech sector.The fall of the USSR doomed the workers. Without USSR-sponsored movements as a constant threat, the capitalists and corporations could ruthlessly exploit workers without fear. The QoL of the US working class would be much higher if the USSR was still kicking today.
The one hope that the US working class has tbh, is if China takes a similar role to the USSR, which is very unlikely. But things can change rapidly, so I would never assume it's impossible.
US has freeways, automobile culture and aviation connecting every major city. There is no way USSR with lack of personal transportation, poor road network could compete in work hours unless workers are residing inside the factory.
