It's a human nature problem and not inherently a gross failure of the system. You can argue that inequalities are made in a capitalist society and I can agree with you on that but if the alternative is socialism / communism route, I'll have to pass as it just doesn't work when both systems fail because they rely on human nature's good will to be effective. Capitalism is the lesser evil. What's happening now isn't capitalism but crony capitalism and corporatism. A wealth tax isn't enough, there should be a strong push from the middle class that momentum is sustained through generations, and making sure laws that govern protect the interest of the middle class more than the few that control most of the wealth.
