I hate to make it sound like I'm pissing on the protesters, but how is it the fault of techies that house pricing is going up?
Look, it's simple, if you study and work hard in something you enjoy, but is difficult for other people to understand, let alone do, yet everybody wants more of then, you will be marginalized because people are afraid of the latent power that you poses. Unfortunately I'm only being half sarcastic.
People who work with technology will be subject to this because of the barrier to entry to work in technology is thinking and thinking is hard work, the hardest work. Technology should be driving down the cost of education but more importantly the availability of information to everyone. So with the realization that "Hey the spy agencies really do spy on us" and "Wow, tech companies are where they get it from" techies become the "How this is happening" or the "instrument", if you will.
I can't speak to the deeper social issues were that caused the spiraling house prices in the first place however, I do wonder how many of the people who protested are prepared to give up the technology tools they were using to organize themselves. I'm not saying they don't have a valid complaint however it's probably valid to ask and understand so there is an opportunity to act ethically about it.
At the same time you got to admit getting around on free private buses with wifi and not using the city's public transport is kinda "in ya face" and bound to make people wonder "well, why are you so special". I can see why people would think that's kind of Morally Superior.
