Earlier quoted context omitted.
Or at least in North America, younger people don't want to live in soulless suburbs where there's literally nothing to do apart from visiting the same big box stores, chain restaurants and bars in exactly same looking plaza.
Until they get married/have kids and do the same thing their parents and their parent's parents did...move to the suburbs. One difference with "younger" kids now is they're getting married later...but once you have kids the suburbs look completely different and it's been that way for as long as there have been suburbs.
My parents moved to the city when they had kids. Specifically to enable a better life for us. More access to friends, better schools, more independence, better extracurriculars, more family time because no commute, etc. It was pretty great.
Living in the city also made college affordable because we could just live at home and walk to school.
