I had Obamacare for 6 months recently. I am happy. There, now you know one person who is happy with Obamacare.
Sure, the premiums are high. For me they became higher because I made money in the stock market. 
Prices is important. What causes that prices is also important. Right now the price is high because people want choice, nearly every treatment option, healthy young people don't pay into it as they should, insurance companies want their cut, drug companies are unregulated and frankly, we're a pretty sick society. Look around. 2/3rds overweight. 16% obese. Eat all the processed food people want, overindulge, don't exercise, then expect our healthcare system to fix it. 
Yep, too expensive. But not due to Obamacare.
