As the Occupy Wall Street protests spread from Lower Manhattan to Washington and other cities, the chattering classes keep complaining that the marchers lack a clear message and specific policy prescriptions. The message — and the solutions — should be obvious to anyone who has been paying attention since the economy went into a recession that continues to sock the middle class while the rich have recovered and prospered. The problem is that no one in Washington has been listening.

At this point, protest is the message: income inequality is grinding down that middle class, increasing the ranks of the poor, and threatening to create a permanent underclass of able, willing but jobless people. On one level, the protesters, most of them young, are giving voice to a generation of lost opportunity.

The jobless rate for college graduates under age 25 has averaged 9.6 percent over the past year; for young high school graduates, the average is 21.6 percent. Those figures do not reflect graduates who are working but in low-paying jobs that do not even require diplomas. Such poor prospects in the early years of a career portend a lifetime of diminished prospects and lower earnings — the very definition of downward mobility.

The protests, though, are more than a youth uprising. The protesters’ own problems are only one illustration of the ways in which the economy is not working for most Americans. They are exactly right when they say that the financial sector, with regulators and elected officials in collusion, inflated and profited from a credit bubble that burst, costing millions of Americans their jobs, incomes, savings and home equity. As the bad times have endured, Americans have also lost their belief in redress and recovery.
