Headsets, Dancemats, Controllers, Paddles, Nice Displays, and Windows Live all cost money for PC's too.
But even with out these we are talking over a thousand dollars to play some current games, just for the basic hardware. While let's pick a console: Wii with a balance board(guessing high $89), 3 extra controllers, 3 nunchucks, and a LAN adapter = $462 and 3 games are included (WiiPlay, WiiFit, and Wii Sports)
It's is fair to say that the experience is better, that is a fair opinion, but it is not cheaper. (And before someone says it: Wii and PS3 can do flash games, so that kills that argument before it starts.)
BTW, There is also the hardware confusion factor, which scares off many consumers.
What exactly is the point of the argument again. PC gamers are high-end consumers, console gamers are not.
I would cite regulation, but I know you will simply ignore it.
