"you will finish a multi-millionaire." Technically I guess you will probably retire at 65 with over 2 million in your 401k. But that's a far cry from most peoples' idea of a "multi-millionaire." With 2 million in your 401k you can draw 80,000USD per year during retirement without having to worry about exhausting your principle. A far cry from lifestyles of the rich and famous. If you had four million then you would be approaching the value of the senior pilot pensions that were lost at the legacy carriers 10 years ago. Pre 9-11 legacy pilots were retiring with pensions in excess of 150k/year PLUS B plans worth 7 figures.
IMHO no 21st century US Airline pilot is going to become a multi-millionaire unless they do it on their days off. The fact that SWA is such a standout with these payrates/work rules is a good illustration of what has been lost.
