Answer: There is no connection between people. There are unifications of markets, banks, etc., and this is the construction of the Tower of Babel (egoism). But it threatens to collapse and bury us under its ruins.
Kabbalah offers the same solution proposed by Abraham 3,500 years ago to the same problem. We must reach unity above our egoism and in spite of it. We will master this method in a good way, meaning by the Light, or in a bad way, through suffering. There is no other way. The predetermined goal of nature is before us, which is to reveal the Creator through unity with everyone.
