Remember the thread talking about how Lillard's parents paid for him to fly around the country with his AAU team? We concluded that his family was middle class.
You can move up, you know. I was on WIC and living in Section 8 housing in Vegas as a kid. By the time I was a teenager, my parents had bought a house and were solidly middle-class. Now they're going on cruises and visiting grandkids while I'm working on a 2nd master's and making 5%er pay. "Started from the bottom" seems appropriate.
