the meaning of 'so long as'
The passage below is from a book, Habits of the Heart.

But this way of thinking about justice does not in itself contain a vision of what the distribution of goods in a society would end up looking like if individuals had an equal chance to pursue their interests. Thus, there could be great disparities in the income given to people in different occupations in a just society so long as everyone had an equal chance of getting a well-paid job. But if, as is now becoming painfully apparent, there are more qualified applicants than openings for the interesting job, is equal opportunity enough to assure justice?The meaning of the underlined 'so long as' left me puzzled and to look up the freedictionary.com.
It seems to be aligned with the meaning #3, PROVIDED THAT, that is, IF.
(Am I right?)

1. During the time that; while:
? We will stay
so long as you need us.
2. Inasmuch as; since:
?
So long as you're driving into town, why not give me a ride?
3. Provided that:
? I will give you the book
so long as you return it.
But there is one further question I want to ask.
Actually I thought the meaning of 'so long as' was 'even if' in this context because there is the relation of contrast between 'there could be great disparities in the income' and 'everyone had an equal chance of getting a well-paid job'.
What do you think?
Is there any chance of 'so long as' being the meaning of 'even if' rather than 'if'?
