It depends on how you define wealth. If it's individualistic capital growth, then community bonding can't be a thing across classes. However, if it's focused on reducing the need to even have capital in each home (think virtually no cost for rent, food, water, power, services because of communal dues that reduce or eliminate the cost for people or an offset paid by those who are wealthier to reduce cost for all), then it'd run counter to the individualistic capital growth because it can't be kept for one person, it's forcibly used to reduce the cost for everyone.

Things like this can exist. From public Internet providers to cooperative housing and grocers—lived by all of this in West Oakland, mostly Black-owned too (which mattered a lot because these concepts aren't new to us historically).
