"Capitalism" as you use the term appears to be an undefined bogeyman rather than a concrete principle or defined economic system. There is nothing about private property or market pricing which necessitates a boom/bust business cycle or other crises. However, there is a significant correlation between credit expansion (fractional reserve lending and government debt alike) and cycles of malinvestment followed by a correction.

When government sets prices for debt, it works like any other price control, shifting how people forecast their investments and business ventures. To borrow an analogy, it's like an architect building a house with an inflated forecast of brick availability. The market process of prices will signal the architect of current stocks, and brick producers of current demand, allowing both to work toward an equilibrium. Government inflation and interest rate manipulation instead cloud reality as long as possible, forcing the architect and builders to change at the last minute, perhaps not realizing the reality until suddenly supply is gone altogether.

This even literally happens with the "skyscraper curse," a cycle where people begin massive construction projects when artificially low interest rates signal high savings rates in the economy, which would normally suggest latent demand for business expansion. However, by the time the new record-setting towers reach their "topping out" phase, the absence of real savings tends to be revealed, and demand for the project evaporates. Hell, I was working as a draftsman for an architectural firm building the biggest tower in a small town, which topped out in 2008.

This cycle is a consequence of government policy, not market volatility. "Greed" and "capitalism" don't offer any real explanatory power, but economic intervention does. Hyperinflation is a phenomenon of central bank failure, not market failure. The cure for the crisis is not a new bunch of bureaucrats trying to run society.
