Grace...It's clearly & undoubtedly a fact that there are multiple "differences in parental attitudes regarding children," among all groupings of parents, from every walk of life and every class, as well.
I don't believe for one moment that income, financial status nor monetary consideration has any particular profound impact on the "attitudes of parents regarding their children." I can't honestly determine what precise response about attitudes you're expecting to garner, by the way in which you've worded your question.
It's my opinion that the vast majority of adults who bring children into the world and become family, all have similar motives & intentions. They are all to prepared to love, protect and nurture their children and provide for them to the very best of their abilities. I do not feel as though their financial status in any way contributes to direct their attitudes in one direction or the other.
It may be that the income bracket of a family creates the basis for how they live to a certain extent, what they possess or how much of it they're able to collect in terms of material fluff. However, other than this, unless the situation is extreme, parental attitudes toward their children remain loyal and loving.
My own parents were "working class" ( very diligent working class) individuals. My sister & I could not have been more loved, protected and guided. In our eyes our parents were the very best and if we lacked for anything, we certainly did not notice for an instant. I can't recall a time when we ever lacked for anything or ever felt slighted or ignored. I can't imagine a better childhood had our parents been as wealthy as Trump!
