"Well, you know, this may be a bit of an overused analogy, but it's really true. The nation's health care system is like a huge ocean liner, and you just can't turn it very fast. It will literally take several years to build the new infrastructure to get people covered who aren't covered now. You can't require people to buy insurance until there's a place for them to go to buy it. And until you have everyone buying insurance, you can't require insurance companies to accept people with preexisting health conditions because otherwise only the sick people will sign up."
