Why should I invest? Can’t I just keep my cash under my mattress?

Investing is the best way to fight the ever-increasing price of everything. A movie ticket cost $2.89 in 1980 and today it cost $9.16. So if you had just put that $2.89 under your mattress in 1980 and pulled it out now to go to the movies, you’re out of luck. Investing grows your money to outpace the rise of prices.
