Tax rates pegged to the income curve

So quite a few folk on here discussing the super-rich paying taxes again…

Have been wondering for a while, what if HMRC pegged tax rates to the national income distribution curve in real time? Your rate set by where you sit on it, adjusting automatically as the distribution shifts. There would be no thresholds for folk to game, and the value would be related to your position in the distribution times an index factor that would compensate for richer people earning less of their gain as taxable income.

Could that actually work?
