So our military is not "high quality?" OK, I guess if you believe that.
Our roads - 99% socialist - are not "high quality?" Do you refuse to use them, so you don't have to live in socialism?
And you're a skydiver. You must be miserable having to skydive within airspace controlled by the socialist ATC, with pilots and planes certified by the socialist FAA, and using parachutes maintained under the same socialist organization.
The reason the US works as well as it does is because we pick and choose which systems to use. Consumer economy? Capitalism. Military, roads, ATC? Socialist. National parks? Communist. We avoid the abuses of any pure -ism by using a mix, with each used where it works the best.
BTW we're not even the most capitalist country out there. On pretty much every ranking of countries by economic freedom, Hong Kong leads the pack. In terms of pure capitalism, Germany wins.
