Well Travis has said multiple times his mom worked at Apple and his father owned his own business:
“My mom worked for Apple, and my dad owned his own business”
His grandparents were PHD’s
“I was in college at The University of Texas and I dropped out. My grandparents were extra educated, my grandfather has his doctorate in philosophy. When I dropped out of school, it was the worst man. They cut me off. I was like a rebel about this education life. I was all bad. I was like a kid man, like, ‘Why the fukk are you so damn bad bro?’ [Laughs.]
He went to elite private schools
I went to private school in elementary and middle school, but then I went to public school in high school man. I loved private school.
It was like the freshest bytches and all my homies were rich as fukk. That showed me a whole other taste level of life. That’s when I knew, shyt is way bigger than Houston, period. Which influenced me to just like tap into other things, stylistically.
He stayed with his Jack N Jill friends at USC
but I knew someone I could stay with at USC. So I was crashing with my homie on his couch at USC.

I don’t know why he tries to change and hide his image. Maybe he thinks it helps him relate to the inner city.
