According to Thomas DeGregori, an economics professor at the University of Houston, in an article published by the Cato Institute, a libertarian think-tank operating in Washington D.C., "it is clear that technological and economic change are vital ingredients in getting children out of the workplace and into schools. Then they can grow to become productive adults and live longer, healthier lives. However, in poor countries like Bangladesh, working children are essential for survival in many families, as they were in our own heritage until the late 19th century. So, while the struggle to end child labour is necessary, getting there often requires taking different routes—and, sadly, there are many political obstacles.
