If your insurance premiums went up by several thousand percent, then you belonged to a company that was heavily subsidizing your insurance before the mandate and decided to pull a political move by removing that subsidy as a way of influencing their voters on which way to vote.
If your insurance premiums spiked 20-30% one year and then have been about 10-15% every year after that, then insurance inflation for you is already down, and you just weren't paying attention to your annual premium increases.
If you were on one of those catastrophe plans that covered very little and cost very little, congrats, the ACA got you out of what was effectively a scam.
