And there you have it: financialization, central bank-fueled speculation and globalization greatly boosted the incomes of the top 20%, while government transfers have significantly increased the incomes of the bottom 20% of households. The middle 60%, who did not benefit from the credit-fueled orgies of speculative bubbles (financialization) or globalization, and who do not qualify for many means tested transfers, have experienced near-zero income growth in the past decade of “recovery” and soaring asset bubbles.
