Earlier quoted context omitted.
If charity works great, why doesn't government-mandated charity work even better? There are a lot of things, like civil defense and firefighting and road building, that historically started working more reliably when they became government-run instead of depending on volunteers or private industry. What makes charity different?
Because socialism has been proven to fail, over and over and over. Roads are not socialism. Roads have not destroyed societies like Venezuela or Cuba. Socialism is when the government decides private property is illegitimate and it fails every time it’s tried. Some amount of socialism may not kill the host but it’s a thing to be feared and wielded carefully not lauded.
The US has spent trillions of dollars over the years trying to convince everyone that socialism can't work by making sure it doesn't work. It seems absolutely unscientific to ignore that.
In any case, I am not asking about the abolition of private property, just about government-mandated charity at scale. Let's say you get a marginal tax of 100% on salaries over $200K, and on wealth over $10M. That's more private property than most Americans will ever have in their life. Is tbat proven to fail? Where and how?
