"another factor that may be holding growth down more than high tax rates"

"there is another factor that may be holding growth down more than high tax rates. And that is the widespread disintegration of the family structure....Government policy can't force people to get or stay married. But it may be able to encourage them to do so....No one knows for sure whether more favorable tax and benefit treatments would encourage two-parent child rearing, although evidence from France (which provides them) and other European countries suggest it might....Today a strong case can be made that we need tax and other policies not just to encourage entrepreneurs but also, to the extent possible, to help bolster family formation."
