I was once at a party a few years ago and, at the time, I think at the time my wife was making around 10k more than me. Some of the people there were her coworkers and their friends, all women. And they knew about me making less because we are always open about our wages.
One of the friends of her coworkers grilled me for like an hour on how I felt about that and all of them pretty much refused to believe me that I was happy with my wife making more money than me. They were mostly just not believing that I wasn't resentful at all, because they had all made more money than their SOs at one point or another and it had always led to fights apparently. I, of course, told them I would love to make more money at my job but it wasn't anything to do with my wife's career or compensation. I also told them she (and all of them) should make more money too.
Shit, I wish my wife made double or triple what I make. She enjoys her job so if she made a lot more doing it, it would be a win-win. My job, I can take or leave, so all I really care about is the pay/benefits. And at the end of the day, our paychecks go into the same accounts (excepting our retirements are separate), so her making more money is just us making more money.
After Anakin's mom was freed she married a moisture farmer and had more kids (or the farmer already had them). So Uncle Owen is either Luke's half-uncle or his step-uncle.
