Yeah, I think one has to understand the man to really get something useful of what he says. He is kind of a cheap man and much of what he says really applies to low-end devices. Some expensive devices may have similar problems to the cheaper stuff but really if you buy a premium device you won't have many of the problem he talk about.
I know this type of person very well. They always have some reductionist approach to things, where for them, the expensive stuff is mostly marketing with added bells-and-whistles and largely works the same. My experience is that this isn't quite right. Some brands do have a premium that is more related to style/status but if you buy some seriously engineered stuff it will work much better most of the time.
He's a midwesterner so some of that's to be expected. But AFAIK KitchenAid is one of the higher end Whirlpool brands. I just checked the orange big box store and the price difference between the KitchenAid dishwasher lineup and that of the Bosch 300/500 series comes down to what's currently on sale.
For reference I'm pretty cheap too but try to be pragmatic. My fridge is a $600 Frigidaire (AEG/Electrolux) top freezer unit. The main selling point was that another youtuber (an appliance repair guy by trade) pointed out that it still has a mechanical timer. They get mocked by appliance sales droids but the top freezer design is significantly more efficient than the alternatives and the lack of electronics mean that you're more likely to be able to repair it.
