In addition to valuing nerds as a way to win against the Soviets, there was also a latent fear of a revolution in America that would be supported by and follow the example of the USSR, which created an understanding that the masses had to be kept placated. And if there was anything too awful about society, it would be criticized by the USSR for the sake of gaining soft power, which provided an additional incentive to fix it. Regardless of all the problems that the USSR had, a world order with competing powers (multipolarity) seems to me to be the only way of keeping the worst abuses of any power in check.
