The stock market isn't fundamentally a gamble. Spending money to buy a share of a company's future dividends is a sound way to invest money and earn a return on it.

The problem with the stock market is when there aren't enough new companies going public to soak up the spigot of all the capital that people want to invest, leading average P/E ratios to increase over time. There is too much money chasing too few earnings. When the underlying fundamentals don't match up, then all that investors are doing is speculating that someone else will be the bigger fool and buy from them at an even more unreasonable price - and that is a gamble.
