Getting Rich is it that Easy?

Is getting rich as easy as it seems as presented by the article article(http://articles.moneycentral.msn.com/Investing/StartInvesting/GettingRichIsSimplerThanYouThink.aspx) by Harry Domash. He suggests that by investing $500 a month that over a 10 year period you will make over $100,000. Also he says you need discipline and time. Who has $500 dollars a month, or the time to invest? Five hundred is a decent amount of money and can be used to buy other things that you may want or need. making this money is not even a sure thing, because you are investing it in the stock market which is never a sure thing. Anything can happen in the market you can make it big or lose alot of money, ecsecially when you are investing $500 a month. So this article actually boils down to one thing, is your time and money worth investing for only a payoff of just over $100,000?
