This is what's so surprisingly scary about time value of money to me. Many "spectacular" investments that double or triple money over a decade or 2 are simply not all that great if you just calculate the annualized return and factor in the inflation.

Back home, I've had so many agents try to sell me inferior insurance and investment opportunities dressed up as insane deals hoping I wouldn't look too much into the details. I was really lucky to come across the folks at /r/indiainvestments who frequently warn about this. But I am sure there are many others who are not aware of these things and fall for them.
