Part 1 (which you are reading) points this out:
And the system is designed to prevent them from escaping [from poverty + precarity]. Every dollar you earn climbing from $40,000 to $100,000 triggers benefit losses that exceed your income gains. You are literally poorer for working harder.
Part 2 is here.
The wealth you’re counting on—the retirement accounts, the home equity, the “nest egg” that’s supposed to make this all worthwhile—is just as fake as the poverty line.
Part 2 points out that all these inflating assets (401k plans, homes, etc) depend for their value on the next generation to ultimately be wealthy enough to want to buy these at a future date at a higher price. The whole "asset inflation" spiral seems like a ponzi scheme of epic proportions since that doesn't appear to be shaping up.
