Did Republicans bring up raising the retirement age tonight?

Sorry I missed the debate. Did they talk about raising the retirement age in the name of fixing social security? How is a larger worker pool with the lower wages that comes with it going to help generations X and Y? And we were just told that we will not be as healthy as our parents. We should lower the retirement age in the name of technological unemployment. A scarcity of workers is more of a good thing then bad for the working class.
