If you 'lose respect' for individual employees because the megacorporation they work for has bad customer service or UX design or what have you, not sure what to say.

Most companies seem to suck in some way or another, reflecting that onto the individual workers just seems silly to me.

They're not "laughing it off" because they're paid well; if they were paid badly instead, what would change? Do people with low wages who work for corporations do something differently here?

For me, myself, and I, we have changed jobs when it became obvious that management wasn't going to change. I had made my very public comments at all-hands meetings as well as other attempts with coworkers to attempt internal changes. When it was obvious we were on the wrong side of the internal motes, it was time to leave. I've even taken pay cuts to not continue to be involved in the insanity. So, yes, I've walked the walk after talking the talk. I did not want to be associated with that company.

I think tech companies could probably do better with customer support, but I also recognize that it's an extremely difficult problem to handle realistically at scale, especially when most individual users pay little to nothing directly for many services. A higher-touch CS model would do better, sure, but that's expensive. It's different imo when you're a store or similar business where your customers are constantly actually giving you money.
