Do you think [inequality] is one of the most urgent problems facing the world today? If not, why not? If yes, what should be the solution.
Yes. I'm a humanist. The humanist philosophy is (among other things) about tolerance, promoting human development, and optimizing social and economic opportunity for the greatest number.
How exactly is taxing the rich going to help or benefit anyone aside from the government who are the only ones who are getting the money?
Do you like the roads you drive on? How about trash collection and police protection?
Why won't you transcend conservative indoctrination media? You can start by recognizing what taxation and government spending do for you and stop berating the process of taxing and turn you attention to how it's done.
The problem with taxing estates after we're dead is that it does nothing to thwart the corruption caused by allowing people to pile up great sums of money while alive.
That's not the purpose of such taxes. It prevents the intergenerational accumulation of wealth, a form of affirmative action for lucky heirs who don't deserve it.
The average American still thinks capitalism is just a dandy idea
I do. Well-regulated capitalism combined with some taxation and public spending seems optimal to me. It served me well and just about everybody else I know.
Competition would be lessened because we would all see how absurdly wasteful it is.
Disagree again. Competition among other things motivates efficiency. Learn to be less wasteful and you increase your profits.
As an artist I can assure that artists are not competing with each other.
Disagree yet again. You're a capitalist if you generate a service (including your labor even if it's an entry level position requiring no special training) or product and try to sell it in free markets. You are competing with other artists, some more successful than you, some less. You and they are competing for the same dollars.
You are likely doing relatively well compared to the average human being. Isn't your life relatively safe, easy, and comfortable? If so, why denounce the economic system that made that possible? You might have been born in Gaza or the Sudan, where they don't have the economic advantages that you enjoy
socialism does not stop anyone from getting rich. It stops them from getting rich at the expense of everyone else involved in the business enterprise.
You just contradicted yourself.
