The operative word is "can." Many get poorer, some get wiped out completely.
The reason they (and anyone actually) has the opportunity to possibly get rich is because they take risks. Sometimes those risks pay off. Most of the time they don't. Risk vs. reward, and that helps everyone.
No one gets rich without effort. Even frauds like Bernie Maddoff and Barney Frank expend effort - defrauding suckers takes work, too.
Many people have worked hard, earned a fortune, then lost it because they didn't know how to manage it. Pete Ham of Bad Finger ended up installing carpet, despite 8 #1 hits, because he trusted others to manage his money - which they promptly stole.
