Most of problems of inequality come down to the fact that rich are allowed to invest into land / housing. One can argue if enormous capital gains should be taxed or not, but the problem starts when rich park their money where it inflates "normal people"'s necessities. Best jobs are concentrated in few big cities, workers have to live there. Rich don't have to live there but they corner the housing market in order to extract maximum percentage from workers' salaries. I don't care how much money the rich have as long as they don't inflate the housing so I can afford to buy my own. Capitalism has learned to extract more surplus value from labour about the moment when worker productivity and salaries started diverging. It used to be that the rich are very few and once they bought all the London property normal people could live their lives. Nowadays there are so many foreign billionaires (China) who either have money or can access cheap debt that they can corner property market in every major city.
