The crisis is the declining percentage of people working who are age 25-54. The labor force participation of people over 55 has been increasing for several decades.

The crisis is no one thing. Allegedly disabled on SSI is distressing. We should be healthier than in the past.
Medicaid membership of healthy work age adults is increasing. They should be working at good paying jobs and buying their own medical care.
Drug use is increasing which partially explains SSI and Medicaid problems.
Our mis-education system is producing people who are not competent to do the jobs available. Seriously, how much is a kid worth who had a poor attendance record prior to dropping out of highschool?
And how much is a college grad worth in the job market if the major was gender studies?
