The space race was hardly a factor is the demise of USSR. Even the arms race wasn't that big of a factor by itself. Soviet Union's economy being incredibly wasteful was what done them in. They produced a tremendous amount of basically garbage goods to satisfy quotas in numbers, so it required a huge increase in base/heavy industries production to drive a tiny increase in consumer goods production. That's why USSR could build great rockets but not a decent car. The central issue is that Soviet economy was perpetually stuck between capitalism and socialism. The workers were expected to have their labour alienated, as in capitalism, but were safe in employment and the wage didn't mean all that much because of all the socialized services (which meant little for non-basic needs in life without a strong consumer goods economy, the issue for ordinary people wasn't that they had no money to buy stuff, they had, but there was usually nothing to buy). So they naturally sabotaged the system by not giving a shit about the quality of "their" products.
