Reply #6: Of course it'd be encouraged (only for the rich though)

Rich people do everything they can do evade taxes. They're also the ones with the most elastic demand (or more freedom to do whatever they want with the money). So if saving cost you nothing and buying stuff cost you a % of your income, then won't you rather put your money in the bank to accrue interest so that you'd have more money to spend in the future?

Since rich people do most of the savings anyways, having them save more would increase saving in general in the economy. I'm just saying that such a plan would hurt the lower/middle class the most since as you said they have to spend almost everything to maintain a standard of living, and we should be aware of it.
