Rich getting richer is fine if poor gets richer as well. If rich gets 100x richer and poor gets 5x richer, inequality increases but that is a desirable outcome.
Unfortunately, many of us (especially Bengalis) have an unhealthy anti-rich-pro-poor tendency at heart. We have vilified the rich. We assume that riches are always acquired by unfair-means instead of hard-work and intelligence. This is tragic since enterprising-rich has been the fountainhead of all civilization-advances.
We Bengalis have paid (and still paying) the cost of this hypocrisy with our collective degrading poverty.
Paul Graham has written two beautiful essays (gap and inequality) related to inequality and wealth-creation.
