If you get rid of the guts and get rid of the muscle "vendors" there is no one left. Just saying.
I would think they would be replaced by men with good physiques that actually work hard to attain them as well as work hard for an honest living. Men with small waistlines and broad shoulders. Men that look like men, not caricatures of caricatures. I realize not all of the "greats of the past" were exemplary examples of clean living (Dennis Tinnerino comes to mind) but there were more than a few that were.
Being a drug bloated mess of mass is neither healthy nor attractive to the public in general. Selling yourself to the highest bidder among the lowest common denominators is pitiful, disgusting and shows just how low the bar can drop in moral limbo. Bodybuilders have to be among the laziest of human beings on the planet. Hustling will never go away entirely but it should never be celebrated.
No one likes a slut. They may screw one but unless mom and/or dad were sluts they will never take one home, male or female, to meet their parents.
