The point of a business is to generate revenue. The point of employees is to do work that helps generate revenue. As such, any decision needs to ensure it has a business case aligned with revenue generation.
Good engineering hygine has significant business value such as in speeding up delivery of new features as well as keeping certain customers happy, but in a lot of cases there is an inability to communicate from either direction (eg. PMs not giving Eng full visibility into business decisions, and Eng not being able to explain why certain engineering choices have business value). If you cannot communicate why this matters, you aren't going to get it prioritized.
Unsurprisingly, at big organizations, communication can take the backseat because communication is hard and at a large company, there is some amount of complacency because the product is good enough.
Edit: Unsurprisingly got downvoted.
The only reason you are employed is to make value (which generally is measured in revenue generated). You are not paid $200k-$400k TCs to write pretty or a e s t h e t i c code. You can make a case for why that matters, but if you choose to bury your head in the sand and not make that case, I have no sympathy for you.
