What if the first 4 people eat 1/2% of the food each, the fifth 1%, the sixth 2%, the 7th 5%, the 8th had 8%, the ninth had 15%, and the 10th had 67%. Under these conditions, the first four and tenth man are paying less than proportional to their share, the 5th is properly charged, and the 6th-9th are being overcharged. Therefore, under these conditions, 6-9 should receive the bulk of any price reduction. The original story fails to mention the critical % received by each man.
Unfortunately, however, the 6th-9th man have become incorrectly persuaded that the 10th man is entitled to most of the reduced price. They are naively afraid that the 10th man will not show up if he does not receive 59% of the price reduction.
You seem to be making the analogy that the man who pays 59% of the total tax bill is getting 59% of the total government services.
The analogy fails by inspection.
I like your math. parsy.
