Not all actors are like that brother, trust me i am one of them.
I could at this very time be making a bit more than what i would be making as a pharmacy technician ( going to become a pharmacist, but right now going through school for tech.) , by joining pretty much all my high school acting friends in acting in ghost hunting documentaries. I had the offer, hell i had people from the producer, to the other actors trying to convince me, and i just couldn't do it. Even though, from a financial and media standpoint it would be the best choice for me.
Actors are not inherent scumbags willing to do anything acting related to get fame and coin, sure some are, but so are some doctors, lawyers and scientists.
And the money is good ( i also had offers from some religious film makers i met through both acting and my last job to do films of a religious nature, and again, turned down because of my morals. ) , because they cost nothing to produce, so the only real expense is actors, i just won't do it.
Please, give actors the same respect you give any group, and not jump to such broad conclusions.
