It's easier to demonize a harmless way to spend time than it is to address larger social issues. And since anime/manga fans are the "other", the person doesn't have to think about his own culpability in creating the gigantic mess that we now live in.
I feel for these guys. IRL sucks. If the holodeck existed, I bet there are many people who'd set it up, start the program, lock the door, and then try to forget about the "real" world outside.
I paid off and cancelled my last credit card. I hate them and wish they weren't so common in the West. They are another way to guide people into being debt slaves.
