In any case, I do believe the current interest rate environment has distributional consequences that haven't been well-studied. It seems the biggest beneficiaries of this environment will be people with lots of debt-financed assets who manage to sell for high nominal prices. On the other hand, a lot of people think rates aren't coming down any time soon (check the yield curve on US treasuries, the 30-year rate is like 3.4%) so maybe this will be a one-time shock where people who took on a ton of debt ca. 2008 will reap big one-time profits as cheaply-acquired assets realize big capital gains.
In any case, I think it's naive to assume holding rates so low, for so long, doesn't have major wealth transfer effects.
