The Difference is Money

In The Purge, they support the ideology that people of higher class are discriminatory towards anyone of the lower class. They show this when the Charlie lets in the random man who was being shot at. The Parents automatically assumed that he was a bad guy. They took the kids to safety and hunted the man down within the house. In reality, the man was a soldier. The dad then left the man alone and decided not to return him to the killers outside. The point is that he automatically assumed that the man was a bad guy due to (most likely) his skin color and his apparel. This is not a true ideology because there are many wealthy people of color and successful people of color. Any person of and race and ethnicity can do anything any other person can do.
