anyone who has read basic economic theory from Smith and Marx and Engels etc, and then read Piketty, can predict the future. the amount of capital has increased to many times GDP, 5-7 times in many european countries, return on capital is around 5%, so 25-35% of GDP is return on capital and that will continue to rise. economic growth being lower than return on capital, means that capital will inevitably continue to accumulate in the hands of fewer people. its math. this is a consequence of having a capitalist system with low growth, high returns on investment, and low capital gains tax.
history shows that there is a breaking point at which this concentration of wealth causes economic depression, stock market panic, possibly war or famines, and then the government enacts emergency measures like The New Deal in the US in the 30s. for example rules which highly tax the rich so they actually pay their fair share. up to 90% tax rate was implemented in the USA after the great depression.
or rules that seperate savings and investment banks so the rich cant gamble away everyones life savings.
these rules are later repealed by corrupt politicians who work for lobbyists who work for the rich and then the whole circus of capital accumulation causing economic crisis starts over.
its no good for anyone. the rich also lose a lot of wealth every time they crash the stock market. its not just the poor who get fucked.
