that's so true. If you work for a company and they lay you off, you have skills but nobody to pay you for them. If you're a fisherman and have oil in the gulf, you have skills but no fish to catch. Can I sue the govt or company because I can't use my skills anymore? Fisherman should have a backup plan too.
There is a difference between an economic downturn (layoff) and a HUGE mistake and negligence (Oil spill) by someone or some company. However, you are correct when saying they should have a back up plan.
