I take it you never had to strike to defend your rights or keep your wage above the poverty line. Must have been nice.
Actually, no. I have always preferred to be my own boss, whenever possible. That way I charge what the market will bear, keeping in mind the need to ensure an adequate hourly equivalent. And if I were to strike for more pay, I'd only be hurting myself. It's not like the clients couldn't go elsewhere (they'd get inferior service in my opinion, but it's ultimately their decision).
