Why on earth would taking wealth from everyone (and it turns into everyone -- There are non-executive wage earners working mundane jobs who pay 50% taxes on their last bit of income and basically pay that on any overtime they work) and concentrating it in the hands of a few insanely powerful government workers ever result in less inequality? You're literally making an overclass of super-powerful people a little bit stronger.

We've done that before -- we gave all the power to people based not on their amount of money but instead their ownership and effective use of horsies and horsie accessories, hard clothing, and pokey sticks of varying descriptions and materials. It wasn't a more equal society back then. The pokey stick hard clothing horsie people still got the nicest houses and could get a bunch of slaves to build big pointy buildings for them.

You're just taking money from the super powerful (and everyone else) and giving it to the ultra mega powerful.
