First off to state that Capitalism has failed is absurd.
Capitalism has created one of the strongest economies in the history of the world.
The average standard of living in the USA is so much higher then the rest of the world it’s a joke.
You can look up the statistics if you do not believe it.
To state that European that socialism has worked in European in countries is also blatantly absurd,
a) Countries have collapsed or are nearing collapse because of it i.e Greece, the Yellow Jacket protests in France b) The US picks up much of that tab for certain thing in Europe such as defense & drug innovation which allows them in turn to spend more on social services (a fact President Trump is trying to change) .c) THere are tiny countries with abundant natural resources that go alot further then the natural resources of a country with 320 million people.
To state the NHS works is basically ignoring reality.
Check up what happens in England if your 70 year old grandfather needs dialysis. Check up the degree of rationing that takes place.
And actually the wealthiest amonst us are the ones who stand the most to benefit from the impostion os Socialism.
A socialist system requires minimum wages and price controls that create a high barrier of entry into the market place.
In other words it becomes really hard and expensive to start a business.
The only one who can are those with extreme wealth which is why in Socialist economies the rich tend to stay rich and the poor stay poor.
So of course the rich like Buffet and Gates are pro-socialist policies you just ensured they have no competition!
