Because it's the ultimate arrogance of taxing people to pay for other people's things. And keep in mind 60% of tax revenue comes from middle and poor class.
The rich people doesn't pay taxes. Loopholes, etc. However, they provide already a better service to the community than the whole poor stratum combined, so why should they? It's a meritocracy. A billionaire creates 1 million jobs, while 1 million people pay more taxes than him, obviously.
I`m talking about honest billionaires, not the central bank and other bankster thief types, they are an abomination.
Healthcare can be private, government healthcare is the worst in the known universe. But unless you eliminate govenrment healthcare, private healthcare will always be expensive. Basic economics 101. (supply & demand)
Libertarianism = freedom. Freedom for the rich to become more rich, and freedom for the poor to become rich.
Socialism = slavery. Freedom for the political tyrants to oppress the poor. And freedom for the poor to stay poor forever.
Deal with it.
