Obamacare represents only about 5 billion of the budget right now but, that is going to mushroom in the next 10 years. Today it is already having a negative effect on the economy through reduced job growth. If an employer has more than 50 employees he is required to provide government approved health insurance for them. The insurance has already become more expensive because of government requirements and companies can't project how much it is going to rise in the next four years because many of the government regulations governing Obamacare aren't spelled out in the bill but, are to be decided as it is fully enforced. Here is a link to a Heritage Foundation study of the early impact of Obamacare:
