Adsolutely. I agree that our lives aren't determined by family background, and we can draw on many other resources, both within ourselves and from other people besides family.
If I overstated my point, it's only because I was pushing back against the idea that education, employment, and a traditional family are equally attainable by all, and if someone has failed in any of these areas, it's because they lack virtue compared to other people (many of whom had more advantageous starting points in life, but supposedly that doesn't matter).
Or in simpler terms, "poor people are poor because they're bad and they deserve it". It's a sentiment that's been very useful for the ultra-wealthy class, and detrimental to everyone else, not just the poor.
