My wife and I have moved every year since we got together in 2003, 4 of those times internationally. Had our first kid when I was 25 in 2008. Yes you're correct, we'd be wealthier and could have afforded our own home by now had we settled. I don't think it's a swap I'd want to make though, money isn't the end goal.
Looking at my peers now, some have managed to purchase places, others not. Usually the determining factor is having had help from their parents, which was never coming our way. We've now scraped together enough to consider buying or building a house in a rural location. But I couldn't say if we'll be settling, my wife is already talking about getting friends to live there to care for our animals while we take off again. It's far easier to move your kids than your cats, although we managed and must have had the most well travelled domestic cat, 1.5 times around the world and 17 US states.
