The whole "disincentive to work" idea is preposterous. If you get $2000 a month for free, do you still want more money or not? It goes without saying that you do. People will always want more money. If this "disincentive" actually existed, businesses would simply fold up upon receiving tax breaks.

What it certainly would do is free people from wage prison - people who would rather not participate in the work force but are forced to for reasons like obtaining employer's healthcare. Obamacare will free many people from this trap in exactly this way - and one of the most pronounced effects these types of things have is allowing older workers to retire who were forced to stay employed, making room for the younger generation.

And people leaving jobs who don't want them but are forced to take them is a good thing. Right now we have 3 people looking for work for every 1 job opening, which drastically skews labor markets in favor of employers. It would be good for everyone if this balance shifted in favor of workers.

The people who want to work will still want to work even if you hand them cash for free. The people who don't want to work shouldn't have to in order to avoid calamity.
