I prefer /I would prefer

[saskia1]

What is wrong in the following sentence? :
I prefer not to go to work in a factory except when they make chocolate.
The teacher in school corrected the sentence in I would prefer not to go to work in a factory except when they make chocolate.
It is my opninion that both sentences are correct English.

We use Present Simple for habits, routines, likes and dislikes, permanent states and things that are always true.
I prefer tea to coffee - this is a fact/real condition, I do really like tea more than coffee.
She prefers to work in the evenings - again, this is a fact.

The sentence "I prefer not to go to work in a factory..." implies the situation is real - that's where the problem is.
The structure "I'd prefer..." is used to express current, general or future preferece; the condition here is unreal.
That's the way I see it.
