What I just can't understand about companies like DoorDash, Uber Eats etc. is that it seems to be a lose-lose-lose proposition. It's more expensive for the consumer with restaurants often raising prices and delivery fees etc; the restaurants make less money per order; and the delivery drivers are often making less than minimum wage and rapidly depreciating their cars. And on top of that, these companies themselves are mostly unprofitable! So who is benefiting here? Where is the true value for society being created? Yes I can get any restaurant meal delivered to my home in 30-45 min, but is that one small benefit really enough to sustain a $60bn market cap?
