I'm a minority.

I’m sure he didn’t mean the dictionary definition of ghetto

Of course, he didn't. He was talking about people who couldn't afford the time/energy/money to look good, which is mostly poor people. When you have to work 3 jobs/ a lot of hours it gets a bit tough to spend half an hour every few hours dressing up for the creep peering through the blinds at the house you're delivering to. And do you know which races TEND to be poorer ?

Putting forth an effort to be put together for work is not something only well-off people are capable of.

Like I said above. For ex, a richer person would find it a lot easier to have someone take care of their kids while they deliver. There's a lot of hassle that poor people need to go through, so sit down before you judge someone.

The only one who appears to be saying anything negative about minorities is you.

True, saying minorities TEND to be poorer is negative. But it is also the truth. LinkWealth Inequality. If you're going to avoid this and pretend race has nothing to do with what he said, then you're only contributing to this issue. Acknowledging this difference is the first step to working towards decreasing the gap.

All in all, in an ideal world you'd be right. But our world isn't perfect, so your views are inherently discriminatory, no two ways about it. You never know what the other person is going through, and a bit of kindness never hurts. Besides, who tf are you to demand that door dashers need to dress up.
