The solution to people not wanting to haul garbage was to pay them enough that it’s worth doing anyway, same as with all the rest of the jobs people really don’t WANT to do. Garbage haulers sure as shit aren’t paid minimum wage, I’ll tell you that right now.

Nobody WANTS to crawl into a sewer and use a pressure washer to break up a massive chunk of congealed fat, human excrement and “flushable” wipes as human waste splatters all over them, but as with most things if you offer an enticing enough reward someone will eventually do it for the paycheck. And there are lots of jobs like this, miserable things that need to get done and nobody wants to do, but they’re important for a functioning society. You might find some people who would do it just out of passion for mopping sick off yet another floor, but you’ll never find enough people who want to do that more than they want to do anything else. You also won’t find people widely enough distributed to cover all the needs, you just can’t assume every single town has a core of people so dedicated to the idea of handling hazardous biowaste regularly to staff all the required positions purely for the love of it.

There are already incentives to “optimize” these awful tasks away, the very means of their completion is and has been to just throw heaps of money at the problem. Being the one to fix it forever for everyone would come with heaps of money getting thrown at you, and yet it still isn’t done. You’re certainly not going to encourage even more problem solving to problems that already exist by eliminating any existing reward system. If they didn’t fix it for the reward of being set for life, they’re not about to fix it just because they had nothing better to do.
