States are putting hundreds of thousands of people directly into jobs through programs reminiscent of the more ambitious work projects of the Great Depression. But the new efforts have a twist: While the wages are being paid by the government, most of the participants are working for private companies. The opportunity to simultaneously benefit struggling workers and small businesses has helped these job subsidies gain support from liberals and conservatives. Congress is now considering whether to extend the subsidy, which would expire in September, for an additional year. A House vote is expected Thursday or Friday. Despite questions about whether the programs displace existing workers, many economists have argued that direct job creation programs are a more cost-effective way to put some of the nation's 14.6 million unemployed back to work than indirect alternatives like tax credits and construction projects. The average duration of unemployment continues to break records, after all, and studies have shown that the longer people are out of work, the less employable they become. Proponents of these national job subsidies, initially financed with $5 billion of stimulus money, say it is better to pay people for working in real jobs than to pay them jobless benefits for staying idle. Placing workers in the private sector is also more promising than giving them make-work government jobs, they say, because market forces can be harnessed to figure out where people like Tremaine Edwards, 35, a former computer technician who had been unemployed for two years before he was hired in May by Gallery Guichard, a private gallery in Chicago, should invest their skills for the long run. Others contend that training and financing will accomplish little if businesses are unwilling to hire on their own. So far just over a billion dollars has been approved to create subsidized employment programs in 36 states and the District of Columbia, according to the Department of Health and Human Services. The biggest year-round program is run by Illinois, which has put 22,000 workers in subsidized jobs (and 5,000 in subsidized summer youth jobs) and has 30,000 people on its waiting list. Most states pay 100 percent of workers' wages up to a certain point. To qualify for the subsidy, workers must have a low household income. They must also have minor children or be under age 21 themselves. Employers seem to hear about the programs largely through word of mouth, and some states actively help match eligible workers with companies. These eligibility restrictions are part of the Temporary Assistance for Needy Families program, created in the welfare reform legislation of 1996, which is now being used to channel the job subsidy money to states. States, cities and local companies have been among the biggest advocates for extending the program beyond September. Small businesses benefit in particular since having an additional worker can make a bigger difference to a company with a small staff. Getting a worker at no cost can also free up cash for other types of investments.
