middle class or whatever it is but when we're coming down to the hard numbers a pledge like hillarhillary clinton's which lt been made by a lot of democratic candidates. >> a lot of people like this number 250,000. >> they like this number but it locks you in and obama made this pledge and he saw this firsthand. he wanted to change the way we help families save for college. help the lower and middle classes by taking a little money through a tax change through certain savings account. technically it would have violated the pledge he made because certain families who earn more than 250,000 would have seen their taxes go up a little bit. he couldn't do it. a week after he said he wanted to, he dropped the whole idea. which goes to show you are limiting the policy choices you can make for actually helping the middle class if you get the definition wrong. >> allison 250,000 put you in america in the top 5% of earners if you are in a household that earns 250,000. i'm sympathetic with your view, we've struggled with this over the last two years. the families we saw all have household incomes over $150,00
