The economic upheaval of the Great Depression in the 1930s brought many of these programs to a halt. Employers cut cultural activities and stopped building recreational facilities as they struggled to stay solvent. It wasn't until after World War II that many of these programs reappeared—and expanded to include more blue-collar workers. Since this time, programs like on-site child care and substance abuse treatment have waxed and waned in use/popularity, but other welfare capitalism components remain. Indeed, in the U.S., the health care system is largely built around employer-sponsored plans.
