If you max out your 401k with B fund contributions (60k/year) for 30 years, starting today, it is *barely* possible to replace the nominal value of a 130k pension, and that doesn't factor inflation which will have reduced the purchasing power of that 130k by well over half.
The government also has a history of threatening to reduce the amount that can be put in a 401k annually, and has also threatened to put caps on the max amount of money you can have in a 401k. Having all of your eggs in the 401k basket is more risk than having two baskets (401k + pension)
