Haha man look, Spiderman is popular because he got a cool ass costume, bad ass move set, and is funny as shyt. Hence the money he racks in are largely from kids toys, merch, and video games.
All that "it's because he represents the everyday man" is some ol outdated shyt that falls apart when you break it down:
Parker is 5'10, slim (or 6 pack ripped post-Spidey bite), college degree, IQ on par with Reed Richards, married to a literal super model, one best friend is the son of a millionaire (Harry Osborne), other best friend is part of a billionaire celebrity family (Johnny Storm), his side chick/thot is a millionaire playboy bunny lookin cat burglar (Black Cat).. I could keep on going..
Now let's breakdown the average height, obesity level, education level, IQ level, bad bytch bagging level, celebrity connect level... of your every day white dude.
Parker is as much a fantasy to them as Captain America. Ol I wish I could be as hard luck as Peter Parker fukkin bad bytches and leg pressing trucks..
