Luckily Congress seems to agree with me:
The House bill, for example, would require that all new policies sold on or off the exchanges must offer yet-to-be-determined “essential benefits.” It would prohibit those policies from excluding or charging higher rates to people with pre-existing conditions and would bar the companies from rescinding policies after people come down with a serious illness. It would also prohibit insurers from setting annual or lifetime limits on what a policy would pay. All this would kick in immediately for all new policies. These rules would start in 2013 for policies purchased on the exchange, and, after a grace period, would apply to employer-provided plans as well.
This one policy alone makes me support the Democrats plan. I am still a bit skeptical though for the plan as a whole. Any reasonable plan needs to ensure that the total costs of healthcare are kept down. So far I haven't seen any sign that the bills in congress take this seriously.
