xexys, you are way wrong on the 401k generating the kind of income of the pension, even if you max it out.
I haven't even come close to maxing out the 401k, but when you count the rising stock market, the rise in stock prices that I own in my 401k, the reinvested dividents and my own contributions to my 401k, my 401k may be my #1 retirement plan if the market doesn't totally tank unexpectedly between now and 13 years.
Their are reasons for my statement of this. First, I get to choose how my moneys are invested, not someone else. Second, all of my money I invest in my 401k are working for only me, not other orphan teamsters. And 3rd, after retirement, I plan on taking out about 1/3 of my dividend income in my 401k every year. Use some of the rest to pay the income taxes from withdrawing moneys from my plan, and then reinvest the rest to continue to grow my 401k. I always hold about 10% or 20% in cash reserves, so that if the market does tank, I can buy cheap. Gotta love the game.
