Under capitalism you are in control of your retirement without government involvement. You plan for it from the day you enter the work force. Neither you nor your employer pay social security taxes, leaving you with a larger paycheck and more money to invest towards your golden age. And your capital gains and dividends are not taxed, meaning that your returns are substantially higher than today. With a little savings discipline and steady work, it is close to impossible not to retire comfortably. Hence, without government involvement, there is no need to factor in retirement planning in your voting considerations.
