I don't see that as a double life if their lives have improved, why should they keep the same lifestyle? Or are you still the same person since you were 5 years old?.
The problem is that most people think that by showing how simple you are or the things you have that's the better way to be accepted by society, that hypocrite one that tries to shape us every single day.
I came from a very poor neighborhood and looking at where I am today I don't miss it whatsoever. The fact I came from that place doesn't mean I have to take it with me for the rest of my life.
