I only have 1/3 of the formula. And I am an above average saver. I doubt that even 10% of the 20s and 30s crowd meet the criteria.
For example,
30 year old guy making $80K needs $240K nest egg to meet the criteria. Let say he starts working at 23, he needs to save $35K a year while paying down his $20K+ college loan. Impossible.
Unless he bought a house on 0% down in 2002 and sold it in 2006.
