Create a market segment where everything costs more for everyone, "employ" countless people -- usually on restrictive work visas and with a limited understanding of labour laws, rights, and protections -- to be the boots on the ground of the operation, pay those people so little that they drive and ride dangerously in traffic, bike lanes, and on sidewalks to eke out more money out of the system, get people used to paying $40 for a burger, and then just... automate the whole thing away?
This is an ethical no-win scenario for companies like Doordash in my mind, but it's one of their own making. Food delivery as a business catering to the general public needs to go away (with exceptions for meals on wheels-type operations serving the sick and the old who may otherwise not be able to get food on their own).
