DJ's make a fuck ton of money to hit play, while most touring bands playing instruments don't make shit. Yeah, it's kind of annoying. Obviously they should make money, but over 100k a show is absurd.
Yeah, I'm sure the DJ is an asshole for forcibly making thousands of people come to his show of recycled beats.
You can use the same fucking logic for a pop punk/alt rock band. A guy can't sing, and the band plays some beginner instrumentation, and 1000 kids are singing along? Not to mention the scene is over-saturated with bands like that. And while maybe playing live is more intensive for a band than a producer, I can guarantee most producers do a lot more in studio than some of those bands, so it evens out, really.
Why aren't thousands of kids watching BTBAM by that logic (actually, there might be), or any mathcore band with insane technical skill?
Why do hundreds of thousands of people come out to see LMFAO who basically contribute nothing to the music?
You can't blame an artist for the demand. Especially in a genre like EDM where there isn't much to do on stage; as the dude says, few people are making new tracks from scratch. You can't experiment on stage when kids are basically at a glorified nightclub where they know (expect, really) the setlist is going to be tracks from who they came to see.
You gotta have different perspective on different types of music and scenes.
