Yes.
I've been working since I was 16 for the same company (28 now). I have 2 defined and vested pension plans, one from the union when I was younger (probably won't amount to much) and the one associated with the management employees. I contribute 6% to the 401(k) with a company match to 5%. I also set aside $150 a month for my Roth IRA account. I'm debating rolling my day-trading account into the IRA which I would have to do over the course of 2 years because of the maximum yearly deposit restrictions. Factor in any inheritance and social security as icing on the cake.
So hopefully even without social security I'll be able to retire somewhat early. I'm actually eyeballing 60. My forecasted replacement ratio was 103% at 65.
I love finance.
