I agree but to be more precise. The needs of each people is based on geography, culture, and age. A need of an infant may be similar to the great elders that depends on caretakers but a teenager would want whatever their 💓 desires, same as the midlife crisis folks, etc, etc. Now add religious preference and ambitions of each into the mix.......well, it starts to appear chaotic but I've seen massive family units thrive under 1 roof but rare will they marry outside races which comes with additional respect of other cultural practices, or conflict will arise but if people really love each other....... all's well and people will choose correctly how to live one's life. Once we elect diplomatic world leaders and not secret society members, it will begin. Love is the key
