What happens with Obamacare actually is enacted….?

What happens with Obamacare actually is enacted. Insurance premiums went through the roof for many people (who have had insurance for years) once Obamacare was approved. What happens in a few years when Obamacare is actually enacted? Are premiums going to shoot up another 30% for people who have already loyally paid their insurance for years? So if Obama wanted to fix the health care system, why are those who have paid for health care regularly getting punished? Didn’t they know insurance companies were going to panic/see opportunity to increase costs?
