Technologists provide tools that can improve people's lives. But I want to be clear that I don't think technology by itself improves people's lives since often I'm criticized for being too pro-technology. Unless there's commensurate ethical and moral improvements to go along with it it's for naught.
Once you become successful people know where you live the type of house you live in the kind of car you drive the clothes you wear and so it would be patronising to go and talk like a welder. Welding's a mystery to me now. You can't go back your life changes every day.
