Techies aren't ruining burning man, techies made burning man. Without the techie demographic, burning man would be overrun with hippies and it'd be indistinguishable from any old Rainbow Gathering. Yes, people spend a lot of money on burning man. An obscene amount, even. However, I'd bet that a majority of that money is on art projects and legit theme camps, and only a sliver is spent on the 'turn-key camps' that people get their knickers in a twist about.
