Capitalism in 21st century

couldnt finish reading Thomas Piketty volume on economics especially the r and g factor for wealth disparity n gdp of a nation based on a factor of above or below no 5 .whereas in the past the elite of the west had inherited wealth based on tangible assets like real estate n factory n etc.,now in new millenial, the wealth of elite group is inherited by childten of tech entrpreneurs based on intellectual propery ie look at net worth of Bill Gates or Jeff Bezos like GDP of small developing nation.the yawning income disparity between the wealthiest 0.01 % andthe rest of the 99% is cause of poverty and instability in the US.without a welfare state like Europe,the wealth disparity causes entrenched social issues like drug abuse,high crime rate,homelessness,poor health care. so this may see why many developed nations are co operating to impose a global tax on monolithic computer companies like Facebook,Google etc to prevent obscene concentration of wealth in a small group of elites n use that to redress the imbalance in wealth redistribution to ensure workers access to basic things like a living wage,poverty,poor medical care n housing.
