Children who come from poor families feel inferior sometimes but they are?

Just as valuable, having the lastest iphone etc does not make someone valuable does your valuable anyway and don't you think these companies are putting too much pressure on families.

I know people who come from poor families and they don't feel inferior at all.

Of course they are and many know this already. Many who come from privilege do not feel valuable either. The feeling of self worth does not come from 'things' for anyone.
