As other posters have pointed out this doesn't really hold up. I suspect it's more that since the Reagan era the USA has frequently had a self hating government, that is a government run by people that believe government itself is bad. This has led to a lot of intentional neglect and sabotage of infrastructure in the belief that "the market" will magically provide public goods. We have similar issies in the UK
