Want to be part of the antidisestablishmentarianism movement? Too bad, I don't know what that means.
My brother mentioned the idea of becoming "corporate". He got himself a regular haircut & took out some peircings, etc.
Here's my off-the-cuff reply:
You're not really corporate. Realize that the idea that how you look defines who you are is a huge marketing ploy, mostly from the folks who want to sell you clothes & makeup. The broader ploy is that buying product A vs. product B defines who you are. They even sell anti-corporate values. Want to reducing the impact of logging? Buy recycled paper. Want to reduce polution from cars? Buy a hybrid car.
In actuality, the only way you can truly disarm corporate power is to not buy from them at all. When they stop getting money, they lose power.
One way to reduce how much you spend is to reduce how much you earn. Earning less has other implications, so then the challenge becomes "discover happyness without money".
Another way is to only buy from non-corporations. It's hard to find people doing things that aren't big money for someone. When I do, I try to jump at the opportunity. My son and I saw a street musician on Sunday. He wasn't very good, but we gave him $5 anyway. I know that 100% of that went to the musician, not the RIAA. We buy milk and butter directly from the farmer (actually we own part of the herd!).
