Thats false equivalency. Billions is the larger number and since a billion is 1000x a million, it would be 3% of their $10000 and 15% of your $10. So its their $300 tax vs your $1.50 tax. Sure they are still better off, however (un)fair that may be, but it was more in tax than you actually hold, by a wide margin.

Or course we could, and should, argue it should be reveresed, but thats just yelling in to the wind at this point.
