An idea I had once would be to transition from glorifying the hoarding of wealth to a sort of leaderboard of who gained the most this year, with very high taxes to keep people from hoarding.

But the dragons don't want their hoards to diminish, and see anything that prevents the rapid growth of the hoard as diminishing it. We need a modern St. George. Likely in the form of an empowered and fully staffed IRS.
