Peter Boettke writing today at Coordination Problem:
We live in an imperfect world populated by very imperfect individuals muddling through with the aid of various institutions, such as those of involved in financial intermediation. The system if based on the rule of law and freedom of contract, will be smarter than any of the individuals that utilize it. Property, prices and profit/loss incentivize, provide guiding signals, and the critical learning feedback so that savings of some will be allocated toward productive investment projects by others. There simply is no alternative to generalized prosperity than through a vibrant capital market.
The idle rich are never really idle is a free market economy.
