The reason speculators can make tons of money on Wall Street, is because they can get people to play along.
You don't make money because an asset you own rises. You make money because someone buys it at that price. (That's the same, I know, but it's an important point to understand - it's NOT just numbers going up and down in a computer, at the end of the chain there's actual liquid money changing hands).
Now we've lived through two financial bubbles right after each other, and one can hope that people will learn that sharp rises in the value of an asset are often inflated, and stop putting their money into the game. After all, those who bet and then hedged their bets on real estate (this time) and .coms (last time) were also (generally!) the ones who lost the most.

Naked short selling doesn't require one to have any money to invest nor any shares. You can still make a lot of money and destroy a company's shares if well connected enough. The price falling on the shares is only produced by the apparent glut of shares offered for sale, they don't need to sell initially to produce a price fall, the offer is enough. Once the naked sale has iterated through a couple of loops and many other offers appear as the stock falls then the price plummets, not because of sales but because of lack of sales.
You make money because no one buys. Traders can make money any way the market moves and if sufficiently skilled and backed can make the market move - it _is_ just numbers going up and down.
