The problem I see is people always want to raid the cookie jar. People want easy answers to crisis caused by previously misallocated capital, and the easy answer is to steal from fixed income, forcing people onto the risk curve.

This then dramatically inflates home values, leading to fewer children, and makes the rich richer via the cantillon effect. It also creates a debt trap via unfunded entitlements, which with fewer children just leads to an avalanche of debt, as politicians promise to keep the system running via more borrowing. Centralized control leads to a tragedy of the commons in our currency.
