So some people speculate or have the insider info necessary to outperform the stock market. But many types of investments are based on paralleling the performance of the stock market (or at least some large part of it).

I believe that the returns on stocks roughly are 4x the rate of inflation, but also wealth has been consolidating at an increasingly fast rate. My question is, to you the lone economist who reads this blog, should you chose to answer it, outside of the margins capital can make from loans how does the whole market outperform the rate of inflation? And would that growth be possible without constantly increasingly wealth stratification?
