I'm not judging you for your way of raising people, i'm merely curious as to why you think someone's choice in hair colour dictates whether or not they will be successful, and that it automatically makes them and their parents bad people? Like i mentioned, therapists of friends of mine have all kinds of coloured hair, unless of course, your idea of "successful" is narrow as all fuck to a select category of jobs. "successful" to me just means you're not doing some menial labour job in the middle of fuck off nowhere, because you can't get a better job, and that you can actually afford to keep your family happy and able to live somewhere without issues.
