From Linda DePillis writing for the Washington Post's Wonkblog:
There’s a good news/bad news situation for occupational injuries in the United States: Fewer people are getting hurt on the job. But those who do are getting less help. ...
“The cutbacks [in workers compensation] have been so drastic in some places that they virtually guarantee injured workers will plummet into poverty,” write authors Henry Grabell and Howard Berkes. “Workers often battle insurance companies for years to get the surgeries, prescriptions and basic help their doctors recommend.” ...
Somebody ends up paying for those injuries, though: taxpayers. When a worker ends up unable to work because of an injury, he or she can be covered by Social Security Disability Insurance, a program that has steadily increased in cost over the past two decades. The rise has many demographic factors behind it, but it looks like the abdication of responsibility by employers may have played a role as well.
