What we call liberalism is really democratic socialism, although the negative icome tax was from libertarian Milton Friedman. Capitalism hires the cheapest workers it can - the ones without kids - if you required a family size based salary. That requirement would doom parents with lots of kids, so tax measures are necessary. We already have them, we are now just negotiating price and adequacy. This approach is so promising it is a wonder the entire RTL movement is not surrounding the White House demanding it! Makes me think the RTL movement is more concerned with the GOP coalition.
