We already have the infrastructure to serve the actual patients, maybe not the best and most affordable way because of the abuse of ERs, but this ObamaCare mandate isn't going to make healthcare better for anyone except to bloat government even further, especially the IRS.
I don't see any benefit to the economy, just more goverment spending, debt and corruption.
We haven't in any way, really, addressed fixing the healthcare problem with this law. In the end, it only reduces the quality of care and increases costs to all who already pay and even for some who currently do not pay. The biggest burden will be borne by the middle class (by costs) and by the elderly (by reduction in quality, timeliness and availability of care).
I don't see this as a stimulus except to the growth of our government.
