"...They are paying into a system that they won’t receive benefits from on the present track that it’s on – that’s the point. I don’t think that’s right. I don’t think it’s fair and I think it’s terrible to ask people to pay into a system that they won’t receive benefits from and that’s why we have to fix it."

This is the mantra of the privatizers;  Bush cited this over and over when he was trying to destroy the most successful New Deal program.

In point of fact even the most conservative estimates show social security having no issues until 2042, and they only address cash flow (current income - current obligations), where the income is the payroll tax.  This completely ignores the fact that SS has been putting its surplus into Treasuries since the last reforms, in the mid 80's, and should the income prove insufficient the obligations will be paid from the accumulated surplus and interest. 

If this were not enough, simply raising the income cap on the current FICA tax to collect on higher incomes will increase the current income and guarantee solvency into the far future.

Paul Krugman had a good op-ed on the subject earlier this year.
