@ned For the owner as much as the worker....
Well no, not always... The owner is taking a risk, the company may not succeed and the owner may not just not see the profits, he may loose his entire life's savings int he venture...
The difference is while the owner may loose everything, the worker is garunteed to be paid for the work he does and will continue to earn a paycheck week after week.
In other words, if surplus profit is not re-invested into the company, both in workers and the resources they need, instead of being hoarded at the top, then everybody ends up losing.
Problem is, that owners keep capital whether the company succeeds or not. Capitalists don't actually care about long-term success, as evidenced. They just siphon short-term gains then pull it out to out into something else when it fails. Meanwhile, workers lose everything, including their future.
