That market independence is the major benefit of a pension.

The other not talked-about benefit is that a public pension is doing the investing and maintaining the financial discipline for you. Most people in the United States are not capable of this, as the savings rate has only been approximately 7%[https://fred.stlouisfed.org/series/PSAVERT], and 5 years down the road Once the Covid vaccine is developed and the economy has recovered it will probably return to those levels. Which brings me to the point that it is almost impossible for 99% of people in the United States to save 40k/yr. At a 10% savings rate this is someone making 400k/yr which is way above average even for FAANG companies. So government work might not be so bad afterall.
