What’s with these companies and their expectations from designers to do everything?

I’m interviewing at a bunch of companies and most of them want a generalist in the product designer position. Expecting to take on every responsibility possible, leaving no room for any sort of work-life balance. Founders/co-founders, listen up. You might be obsessed with the problem you’re solving. Do not expect others to be equally obsessed. With all due respect, we’re here to look after ourselves and our families. You disguise these additional responsibilities as “learning opportunities” which is absolutely bollocks. You don’t even offer to pay accordingly. Just needed to rant. If anyone else here has a different point of view, I’m open to changing my opinions.
