Why Are People Too Lazy To Use Oil Paint?

Why are so many people too lazy to use oil/Alkyd paint?
Really, washing your hands and brushes with a bit of Varsol is not a terrible chore. Or here si an idea…toss the god damed brush, they are cheap and not really reusable anyways.
Alkyd paint is so much nicer, its thick, water proof, better adhesion, and less prone to wear from foot traffic?
Why are people too lazy to wash with varsol and too delicate to handle the fumes? Dont you want your paint job to last?
Oh, and on the same note, why are so many people too lazy to prime?
I do this kind of work on and off, and it never ceased to amaze me how lazy people are and how much shoddy work they do out of being lazy.
