How many people were uninsured before ObamaCare came about?

Before Obamacare, a lot more people had jobs including myself. Those jobs provided their insurance. Millions of people have LOST their insurance due to Obamacare. McDonalds hired 62,000 people AFTER getting a waiver from having to change their insurance coverage for their employees. They can't afford it. Plenty of people are noticing that Obamacare will turn this country inside out, upside down, and add to the destruction of the US economy that is the result of this administration and their good intentions gone bad.
