Ok so how does a cancer kill its host?
It grows until it consumes so many nutrients that the other living cells don’t get enough. The host literally starves even if he eats plentifully.
The same applies for the US: The billionaires are not only hoarding wealth, but by doing so they’re crippling the economy for workers and everybody besides themselves.
There is no goal other than to keep taking. They couldn’t stop even if they wanted to. It only ends when life becomes so miserable for enough people that violence becomes the only answer
