Yeah they've done lots of studies but there's still controversy over just how high the tax rate has to be for it to act as a disincentive but there's not much question that at some point it becomes a disincentive.KFunk said:Has some kind of sutdy ever been done on the relation between tax brackets and motivation to earn money. Even if high tax is a demotivator I would argue that the motivation of money is still extremely high. I reckon you could just about as easily argue that the 50% tax rate motivates them to earn twice as much.
