The way to do that is via profit sharing/bonuses - converting payroll from a fixed to a floating expense, essentially.

I disagree that "companies" have become more callous. The general public want their cheap stuff, and they don't really care. The press is full of horror stories about sweatshops every week and yet, everyone wants their new iPhone and their new trainers and their clothes to wear for a few months at most... What will it take to effect a change in the mind of the consumer?
