Even if that were so, (any citations there? The assertion is almost laughable.), it's not what the argument being made is saying. The argument is being made that these institutions are somehow providing MORE value to the successful, so the more successful owe more for their use.
Which is simply not true. If a clever, successful person is somehow making more or better use of these tax-funded services, that's the side effect of him being clever or successful, not that the service has provided him some sort of hidden value that the less successful cannot take part of, and for which the successful person "owes" more because of.
> You aren't punishing them for success.
Simply saying that doesn't make it so. If you make more and are more successful you are taxed at a higher rate. This is the very definition of being punished for being successful.

Can you list some? How is the $10 I pay in taxes that gets allocated to some department of the government any more or less than the $10 that someone else has paid, at a different tax rate? It might be non-linear to the PAYER, but that's irrelevant; it's exactly the same to the PAYEE.
Whether or not someone can /afford/ a higher tax rate based on income is irrelevant and stems from an emotional argument, not a fiscal or economic one. <snark>And a sour grapes, juvenile "IT'S NOT FAIR!", wealth-redistribution based one at that. My 9 year old has these sorts of ideas.</snark>
