What if Wall Street Crashes Tomorrow?

I think most of us would agree the the stock market system,  as first intended, is not working in the manner it was created or intended to function.
The basic premise of the "stock market" was a place for a business to raise capital so businesses could grow, flourish, create products and jobs and return an investment to those who invested in them.
For most who understand the market these days, that is not how it works anymore. Most of what goes on revolves around speculation, perceived future potential earnings, and for the most part, it is a gambling enterprise based on stock price manipulation. We saw that in full view when long standing good bank and insurance businesses were demolished due to their wayward ways in the last crash of 2008. Only those who bet against the market made money then. 
While those are the rules, and they have every right to do that, that is not how it should work. That does nothing for society as a whole. When real businesses and companies crash, real people lose real jobs and real hardships occur.
Obviously, something has to change. Some would have the whole system revamped on the spot. 
Here is the reality that most of the 99% don't want to hear. If Wall Street crashes tomorrow, there would be mass chaos. If you think it is bad now, you have no idea how bad it could get. Every man and woman would be affected. Unemployment levels around the world could reach 40% in a week. 1929 would seem like a picnic compared to that. A large portion of the U.S. population would lose their homes and be on the street. Countries like China would call in their loans and the U..S.  and other Western countries would default, much like Greece is doing right now. 
Does Wall Street need to change? Yes,  it does. It needs to get back to the purpose it was created for.
Can that be rapid and drastic change. No.
If the goal is to make the system better, it simply cannot be done in that manner. The market might be fixed if that happened, but the whole society would crumble.  
That doesn't do anybody any good. The sad reality is that we just have to live with the fact that some know how to play the game and will get rich off the system. Taking them down just to prove a point will be little salvation if you are living on the street next to them.
