The economist has said this for decades.

Meanwhile the US life expectancy has been decreasing.

And countries with huge governments like France have been doing just fine.

Also running a similar deficit than US.

Even being libertarian, I have common sense to acknowledge that those takes are plain stupid.

It's all about how the money is spent, not if it's public or private.

I bet most money spent by the government in the US is in entitlements, not infra or any kind of subsidies to key industries. So yeah, very inefficient!
