As most people have expressed, there is a lot of information to take in while trying to understand the Affordable Care Act. As a result of all the confusion, anti-ACA advocates are easily able to convince young people that don't really understand the law that it is unnecessary and harmful.
People care about laws when they know it can have a positive or negative impact on them. Why not start using social media accounts -- the most effective and guaranteed way to engage with young people -- tailored to specific states/regions that explain the positive economic benefits the law has on their community? A strong economy gives way for a more prosperous career path, and finding a job is the number one issue young people care deeply about.
If milennials start comprehending the relation between the ACA and the economy, perhaps they will start caring about the injustices that insurance companies have practiced for so long.
