Tax breaks for the middle class is really not worth discussing considering most get back more than they paid in the first place. It's essentially another form of welfare. As for everything else Obama proposed, they are essentially micro-level proposals and won't make any significant difference in the aggregate. This was just a method of forcing the Republicans to denounce everything he does to make them anti-middle class for the remainder of his term.
On a side note, healthcare is still hilariously screwed, despite how libs and special interests decide to twist the numbers in favor of the ACA. 30+ million without insurance and yet ACA can barely shell out subsidized insurance for 9m. On top of that, healthcare costs haven't really changed. 7 days of paid sick leave going to make a difference? Not really.
