Similar for me. I was told this repeatedly when I was younger, but all I heard was "If you get rich and successful then the wealth will corrupt your values". I'd like to think I could keep my values if I became wealthy, because I know what it's like to be homeless and hungry. But money does change people.
In my experience in Korea, it's the opposite. The people who grew up with real hardship are usually the first to hoard any and all wealth that comes their way.
