I think you might be overlooking a couple things
For one I think you should add ASDA to your story.
I certainly applaud anyone who can make a fortune. Those four Waltons didn't make anything.
Was it daddy Sam's prerogative to give it to them? Sure it was.
Should they be taxed more than 33% for it? Absolutely. The costs of maintaining society so that the unwashed masses don't break down their gates and take everything is, at a guess, certainly much higher than what they're paying.
Those 1%ers who complain about high taxes now should be glad they not paying the top rate during the Reagan, Eisenhower, or Hoover administrations. (Republicans all, in case you don't know.)
And it's Scrooge, not Scrouge, McDuck. Check your Dickens.
