Cities are like a wall that block people off from viewing the true reality of life... They put huge buildings up that create "bosses" and "corporate culture" and "stores" which all feed being over worked and the ideals of constant desire for more (consumerism). You can only work in a city if you adopt the mindset, which truly is "grind till you die" to your detriment.
People need to burnout in order to fuel a world like ours, it's no different than in the past. Some would say there are simply "too many people on this earth" to escape the constant drive for workplace-related abuse, social inequality, criminal behavior, and injustice when people are tightly packed into cities unfortunately. You realize a different way of living when you escape the city and live in a less populated environment that fosters more of what really matters - Family, Health, Creativity, Communication, Mental Well Being, Nature, and Less of a Competitive/Combative Enviornment.
Once you visit other (more rural and natural) places where people live in communities, where the pace is much more slow, like farms, mountains, beaches etc, most thoughtful people pause and realize that none of the "concrete jungle" accomplishments really matter in terms of life merits. Unfortunately, the poor and working classes rarely if ever have a chance to escape on a vacation, so they are burdened most by burnout... That burnout feeds bad things like suicide, drug abuse, poverty, depression, crime, etc, while the rest of society simply remains ignorant to the root causes of those things. Not to say that those rural and natural places are perfect to live in, but they allow for less distraction from meaningful life goals in many ways over city environments.
Many (wealthier middle class) people occasionally get to take that nature vacation at points in their life, and then later return to the city grind, hoping to recapture the vibe in retirement, but they forget the true motivation as they get behind the city walls again often.
The super-wealthy buy homes in relaxed environments at their whim... And many even work in the city without leaving their super comfortable beach and mountain "vacation" houses. Some would say that's one of the major reasons they often think far beyond the constraints of their (less paid) employees who live in the city and work in the city office... Not because they are "smarter" it's possibly because they are far more often less "mentally distracted" and weighted down by finances, work commutes, and burnout culture of city living.
