OK, how much did you say you have in there? $150k? Don't remember but let's use that as an example. You're withdrawing $2000 a month to live on and getting 4% interest. That's $24k withdrawal and $6k interest first year. Over next 10 years you're steadily drawing $24k but interest each year is less because of less principle. You'll eventually run out of money and won't have anything to leave kids. Of course you won't because you have full traditional pension too, don't need to touch portable unless emergency. However regular employees today won't have the traditional to fall back on. They'll need that money. Hopefully they were earnest in saving in their 401k. However at 70.5 years old you will be required by law to start withdrawing. Can't leave it untouched forever. And your kids won't be able to leave it in there. They aren't the employee. They'll take a substantial tax hit because the money hasn't been taxed. And as your traditional pension has no COLA it will be worth less over time. So you'll need that extra income eventually if you're healthy and live well into your 80's or longer. So don't count your chickens. The government and the medical community are very good at separating people from their wealth.
