Insurance cost will rise.
Companies may decide to drop insurance coverage, since it is higher than penalty.
The net side effect is that.
- insurance cost will rise
- govovernmet and state health care spending will rise (to subsidize the currently uninsured)
- health provide may (maybe not) get a break
I would imagine that Obama will cover illegal immigrants as well.
In the end, still there will be a lot of people not insured, since they don't file tax anyway, and hospital has to treat them anyway.
