Perhaps a benchmark on income should be established. I do not live in the USA but I will use it as an example:
The President of your nation holds the highest office of in the land and is paid a wage that should reflect his office. Set the benchmark at 99% of his income. Anyone exceeding that amount would be taxed at 100% on the excess. Sports and movie stars would then earn closer to what they are worth and with the extra income the government could make both health care and beer free for everyone.
