I often find that even investors can be reasonable.

Most of the problems in tech are of the employees own creation. Unreasonable requirements and unreasonable timelines, often coming out of thin air for no reason other than some middle manager's political interests.

It is super hard to fight against it, and it's even harder to demonstrate how forcing tech to work more than necessary is bad for business.

Small businesses deal with it by being small. Big companies are just chaotic complex systems where you don't have much of a choice.
