Big Brother(s) = Billionaires

That would make the Brotherhood the large corporations they control.

The U.S. government consequently encourages mega-corporations through taxes and regulations to crush small firms by making it harder for them to grow. That somewhat locks-in the existing aristocracy to be less self-made (as Bezos himself was, but his children won’t be).

Elected politicians overwhelmingly support this because most of their campaign funds were donated by super-rich individuals and their employees and other agents. It’s a self-reinforcing system. Super-wealth controls the government, which (along with the super-wealthy and their corporations) controls the public, which reduces economic opportunity for them. The end-result is institutionally reinforced extreme wealth-inequality, becoming more extreme all the time.
