Congratulations and count yourself among the lucky. But if you cannot appreciate that things will not be that way for many employment situations then you don't know how lucky you are.
The default in my industry is exactly as you describe. The only reason it isn't so for me is because I refused to give over my autonomy and have remained in touch with my intrinsic motivations. The job/role/industry is irrelevant as far as causation, I'm just mentioning mine for context.
