If Medicare and Social Security are going bankrupt then why not?

[Steve]

Calculate to what level FICA and Medicare taxes would have to be raised in order to keep those programs from going bankrupt, and then then raise the taxes to those rates.

Why are cutting the benefits or destroying the programs the only options, but raising the tax rates are not an option?
By the way, I do pay taxes, including FICA and Medicare. And I want Medicare there for me, not some Vouchercare system that they name Medicare.

And, households who don't pay taxes, don't receive Social Security or Medicare, so they're not affected.
