Nancy Folbre references some research my colleagues at Levy Economics Institute and I have done: Improving Home-Care Services, Creating Jobs - Economix Blog - NYTimes.com. I'll wait while you go read her post . . .
Long story short from our research : $50 billion would provide early childhood education for the entire country, employ more people than $50 billion in infrastructure construction spending, and provide those jobs to people from the lowest income families. More effective and more equitable than most other spending in last year's too-small stimulus package.
