Not only has the owner-occupied rate stayed near constant, but that rate itself is an average of all income levels. If one just looks at the rate of homeownership among those making more than the median income (family/individual) ~$74K for a family (~55K individual), that number jumps up to 79%.
Given that this number doesn't take preferences into account, I think it's pretty reasonable that almost everyone (>80%) making at least the average (median) salary owns their home.
