> The pervasive myth that hard work == wealth needs to die.

The purpose of the concept is to push kids from a young age to be industrious. You are much less likely to become wealthy if you sit around doing the bare minimum.

Putting in an significant effort isn't a guarantee, but it does increase your chances from whatever the baseline is given your context.

The concept doesn't claim that wealthy people all worked hard; everyone knows you can be wealthy without having worked at all, such as through inheritance or the lottery!
