Sometimes the best person to seek advice from,(when designing an anti-theft device-for example), are the theives themselves. Muggers, rapists, computer hackers, etc. could all offer valuable insights into various ways of 'protecting' yourself from 'harm'.
Pointing out social and moral decay requires no special degree. We see it all around us. That a large, video gaming personality would like to remain in the spotlight while instructing us on virtue, all-the-while getting paid, irks me, in light of the amounts he's squandered and profitted from, in the name of self-entertainment.
You want to preach to me, then take a vow of poverty. Virtuous acts are not attached to the profit motive unless you can somehow attach virtue to helping a stranded motorist by calling a towtruck and then asking them to pay for the 'minutes used' on your cell phone. This is how I see the man.
Those who live a cloistered life, hide themselves away from the rest of the world, and are not tempted like the rest of us. By reducing their exposure to temptation, they remain more virtuous, perhaps. But, that shouldn't necessarily make them more revered. Because the mortals among us who suffer through the tempations, have grown into stronger and more virtuous human beings, because of our sufferings. It is learning the lessons, that strengthens us.
