That's awful. That happens when bureaucrats, who often don't understand the most simple basics of economics, mandate socialist rules to private companies. The companies affected by these policies will now just fire people to keep staff cost on the same level as before, period. Thus less people trying to fulfill the role of the same amount of delivery guys as before. And such more stress to fulfill more orders in the same amount of time. In other words the situation for the delivery staff is worse than before. Doordash will now have a much higher staff turnover rate where drivers quit after a few months due to e.g. burnout and are replaced by new workers who intend to take the high wage but only for a few months. Serious long-term employee positions are now gone. And as always nobody forces anyone in any way to work for doordash - people have their own free will to choose to work for doordash for any dollar amount that is offered to them.
No minimum wage is what creates competition between companies, all industries affected by minimum wages already have and will have shitty wages for ages to come. Switzerland as an example is a country where cleaners (CHF 4K a month on average) without any serious education earn a bit less than a well educated professional mechanic and 2x more than a local branch bank employee in Germany, simply because of no minimum wage restrictions (also after monthly living expenses in Switzerland which are relatively high in certain aspects).
