"Profit is the signal that a need was actually satisfied by voluntary choice"

"What’s always evaded when people say 'capitalism is about profit, not needs' is that profit is the signal that a need was actually satisfied by voluntary choice. 

    "No one earns profit unless others judge the product or service worth more than the money they give up. ... 

    "When they say capitalism 'fails' to supply needs that aren’t profitable, what they’re really admitting is this: People do not value those needs enough to sacrifice their own resources for them."
