Look at this graph of inequality. From the Human Development Report 2013.
People complain, with some justification, that the rise in inequality in income is bad. Hmmm, ok, I will give it a bit of credence but generally, don't give a shit. As a libertarian, you sow what you reap and as long as there is a minimum welfare state, you can earn what you want. But then here’s the question, what if rising inequality in income is accompanied with decreasing inequality in health and education?? Will you be willing to make the trade off? Or is there any relationship between these factors?
