I agree. I'm having a hard time understanding how raising the salary of delivery workers to what an entry level doctor, engineers or lawyer is going to solve the problem. There are two things that might happen, either all the other salaries in the world will then also increase (and thus services too), keeping the wealth disparity the same, or, since these delivery companies already operate on such thin margins (GrubHub net profit for past years have been negative $millions), they are going to pass the cost to the consumer. It creates an interesting problem where then it's too expensive to get delivery so you don't order food, which means less delivery jobs are needed so people are laid off, preventing people from making money. Also, from what I've seen, most of the workers seems to be immigrants. While I'm not saying we take advantage of immigrants, but these low barrier to entry jobs have always been helpful for those who have complicated statuses.

I'm not bashing any delivery worker (I used to work at a wings shop in my youth), but the amount of interaction you spend with a delivery worker is usually minimal. It doesn't require any formal training and neither being a bad one is going to affect whether you are in the mood for Thai food.
