And I am strongly disagreeing.
But the point is - they are commuting into NYC just as folks in your neighborhood are. But the folks in your neighborhood, for the most part, have a tax-deductible housing asset (that usually grows in value), pensions, health care, maybe a little stock, perhaps some vacation time, and a car or two that usually runs. In other words, far more in common with the family earning $1m (but working), than with the median family, which often has none of the above. Oh, and maybe a decent public school to attend. Three-quarters of the children of the median family won't be attending college at all (some will be contributing income to their families)(and about a quarter or so won't have graduated from high school); many of the rest will be at the community college part-time or in the evenings.
Oh, and savings toward college over the past 20 years (like the $1m family)? Forget it. More likely paying off uninsured medical expenses over the past 20 years.
