All King Solomon did was asked God to help him to be a good leader of God's people. He didn't ask for things, he asked for God's help to be the best he could be in the role God gave him. And God blessed him with what he asked for and then went above and beyond to bless him with riches that made him the wealthiest man in the bible.
Holy Bible, King James Version, 1 Kings chapter 3 verse 3
So I would say... Favor IS Fair.
It's like when a person chooses to go to college and spend 7-10 years studying and they get the degree, then they get the great job. Now along comes somebody who says that they just got lucky, or that they knew somebody, or that it was cheating or not fair! The Truth is ... They EARNED it. and the success was not earned 'overnite', it took many years of hard work!
So again... Favor IS Fair.
