I'm not sure I understand this, it doesn't feel like what I have "lived" for the least 30 years.
Median real income might not be down statistically, but the purchasing power of professional incomes relative to housing, education, and major life costs clearly feels lower than it did in the mid 90s. An inflation-adjusted six-figure salary today does not deliver the same lifestyle position it once did.
Man... healthcare costs, too. Hell, even computers! Raw computing power per dollar is cheaper than ever, but the minimum spec required to function professionally has risen so much that the real cost of staying technologically current feels higher.
