IMO, the democratic leadership wants to subsidize American industry so they can control it, much of which revolves around pandering to unskilled middle class workers. The dems agree that they need to make great money liked their skilled counterparts. This is their anchor to office, if they alienate the working men/women their cushy power trip will grind to a screeching halt.
Evidence of this is how Obama and his crew have devised "trickle up economics" based on creating what I call "giveaway" jobs in hopes the money flows up and strenghtens businesses (you can tell he wasn't a plumber
)
