Maybe I am alone but I disagree and agree here. I agree that rich people know how to spend less but one does not become rich on savings alone. It takes the ability to make value out of nothing whether it be your the lord of feudal lands which you rented out to peasants or online book company that made buying and selling slightly easier. Those people made money because they made value. Not just saved value.

I think this well intentioned advice can actually act as a hindrance to escaping poverty. If you spend a ton of your time walking through the grocery story saving a couple bucks buying cheaper eggs you really lost a lot of your potential earns in that time you spent. Because this is a behavior you will repeat and repeat and the accumulation of this time is a net minus on what you could have saved if you spent that time learning a valuable skill. I think that's why any major uptick in peoples wealth is usually (not always) correlated by education. Places with smarter people tend to have more money because smart people generally speaking know how to create value.
