But needless to say, that's a rather small population. The article is cherry picking this small population[3] of kinda-sorta-unfortunates (they're still making $120k a year!) and using it to argue against a bunch of government programs that provide real benefits to people with a fraction of their income.
Could things be tuned better? Yeah. Benefits programs are filled with this kind of unintended side effect. But to write this kind of blanket argument cautioning against them seems awfully partisan to me. It's a fairly typical right-wing Forbes editorial in journalism clothing.
[1] $120k per year is in the top 10th percentile or thereabouts -- it's at the very edge of what most people would consider "middle class".
[2] NOT simply a lower paying one, as the article implies. A lower paying position is still full time work, after all. The contention that making less is "bad for the economy" isn't really sound. Downward wage pressure in high-paying jobs is a good thing for the export economy and a good thing for profits (companies are paying historically high fractions to their most highly compensated employees).
[3] That is: gate the income to a small range just big enough to be affected by the loss of financial and mortgage aid, but not so big that it dillutes back to the overall tax rate of ~38%. Then pick out only the people who actually need that tuition and mortgage aid: parents with both underwater mortgages and privately-school children in the right 4-year age range. If this isn't cooking the books, I don't know what qualifies.
