healthcare in this country is a mess. I am about to fight with my dentist. Because the guy had given me a certain estimate for an implant but now it seems he only gave me his side of cost and I have to go and dole more money to another general dentist for a crown. This Ahole has not even been upfront on how many procedures/visits this implant entails. So he will schedule something and all suden he is ordering xrays and asking if I am ready for more surgery. Bottomline Obamacare allowed the doctors and pharma to continue with the party
On the basis of the evidence given, I'd say it is your implant guy who is a mess. He should have been upfront with you on the need to go elsewhere for a crown. On the other hand, he might have assumed that you were referred to him by a general dentist, who, presumably would have told you that you would have to return.
In general, things like implants are a tricky matter that I would not use to judge the insurance system: they can be a real need, or they might be "cosmetic" surgery. And they are never cheap. If you take a country such as Canada, which is generally judged to have a good healthcare system, public insurance makes a distinction between a guy who has had a tooth knocked out in a bar-fight and wants to go back to looking good and a guy who has a real need. The situation is similar in a few other places I can think of.
As for Obamacare, if it made insurance available to those who did not have it and would otherwise not have it, then I'd say it's a good thing, even if it has "allowed the doctors and pharma to continue with the party"
