What if everyone sells their shares and the stock market “breaks down”?

baerchen80: What if everyone sells their shares and the stock market “breaks down”?
What would be left of our “economy” that we can work with to build a “new system” without factors unknown to the public that manipulate the value of stock shares? Are there any (scientific) scenarios for an event like this or possible future systems similar to our current public understanding of economy, but without manipulation?
Sure there has to be a buyer, but I understand shares as being given out by companies to get spending money, offering a possibility for share holders to “democratically” decide what to spend that money on. Trouble is, there is always some percentage of shares that “all of a sudden” is sold by who knows and then the value of shares drops. I deliberately call this (active) manipulation.
My actual question was trying to aim at possibilities to avoid such manipulation, be it through not buying/having company shares at all (sell them all – back to the company) or some other solution, because obviously the stability of the stock market is highly important for the worlds wellfare and should preferably not be subject to any speculation whatsoever.

For every seller there must be a buyer. That doesn’t sound like a breakdown to me.
