Healthcare was not better before the Affordable Care Act (Obamacare). Insurance companies were abusing the system and charging people exorbitant amounts for routine procedures. People were being denied care and insurance. For example, anyone with a pre-existing condition like cancer would not be allowed to buy a new policy from an insurance company unless it was extremely expensive. This left many people without insurance and the medical treatments that they needed. The Affordable Care Act is getting rid of pre-existing conditions, requiring 10 routine medical exams and procedures be covered including annual exams, and closing loops in Medicare coverage. These are all good things that make it better than previous healthcare.
Before Obamacare, people could be rejected from receiving health insurance for pre-existing conditions that they had no control over. Any system that can reject people from receiving the means to get the care that they need is not a just system, and one that needs to be revamped. Obamacare is not perfect, and it still isn't totally settled yet, but it is leagues better than the corrupt system we were at the mercy of before.
