I think they're saying the interaction effect of doing drugs, drinking and considering oneself a victim is negligible on overall success.

It doesn't seem like a bold claim to me. I've known plenty of poor, struggling working class people. The only impact drinking or claiming they're a victim have is influencing how much fun they have at parties.

I've happen to know plenty of wildly successful people who also drink and/or think they're victims. Again, primary effect I've noticed seems to be how much fun they are at parties.
