Provide early and effective support. Invest in public services, housing, education and training, and the NHS, and it will pay off. This is relevant for disabled people but also the other social problems discussed on this thread.
Employer attitudes is another issue that needs addressing. Many businesses no longer want or can't afford to provide training on the job. They also don't want to hire longterm unemployed or disabled people. They don't want or feel unable to make adjustments or offer flexible work options. That needs to change. Encourage and support businesses to do this.
Agree with this, @Againname
I'd also add, go after men who don't pay child support when they opt out of family life.
Where I live, the state goes after deadbeat fathers both within the state, in other states, and in other countries. The state tracks them down via postal records, the National New Hire Reporting Service, the Federal Parent Locator Service, the State Parent Locator Service, the state Department of Employment Security (unemployment), and the Secretary of State Office (driver's license and other ID services).
Wages and monetary welfare benefits can be garnished, non custodial parents can be forced to pay for health insurance or add children to employer-provided health insurance, and the courts will issue a warrant for arrest or for contempt of court if a parent goes two months overdue on payments.
