I Thought Democrats Were Pro Choice

We are constantly told by Democrats that Republicans should be tolerant and pro-choice. Its an individuals right to choice and those rights should not be infringed upon.

How come Democrats are not pro-choice on Social Security then?

In addition, the poll shows most Americans favor giving individuals the “right to choose” between keeping their Social Security contributions in the current system and putting a portion in an investment account, and just over half say they personally would want the choice to invest some of their contributions.
