Jobs don't matter. Efficient production matters. Obamacare is a massive misallocation of resources to inefficient uses. Allowing those resources to be allocated to the uses that people want the most (i.e., that produce the most profit) will allow a larger amount of desirable goods and services to be produced (while less-valued goods and services (i.e., government bullshit) will be produced less).
The result will be a net benefit to the US and to the world (and a loss to government functionaries and their shit-eating hangers on, which is always good).
