Minds are open:

At a fundamental level, Americans still favor the concept of privatization. Findings from a variety of recent questions asked by numerous national public opinion organizations confirm this. When asked about privatization plans in general terms -- with little in the way of specifics, or pros and cons, in the question wording -- the public is slightly in favor of, or at least divided over, allowing a portion of Social Security contributions to be invested in the stock market.

A good bet is that the shriller the argument, the less chance it has of Americans embracing it.
