Fxxk compound interest

Just read some tutorials in investopedia.com. Like all other investment salesmen would say, one REASON to do financial investments is compound interest. What the fxxk? I believe this "reason" sucks, and is no longer valid in this modern 21st century.

Ok, maybe we are noobs who don't know how to buy the right stocks at the right time, and maybe we are not aware of many other ways to make effective use of our money. But hey, our money is not under the pillowcase, they are in the bank earning compound interest, however small it is. It is no way "compound interest" is the reason why we should learn various investment skills; it is simply the potential return that we need to emphasize on.

Can the people who write articles, as well as those financial counsellor and salesmen, be more creative, heartful, and throw away the old-school texts >_<
