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.
Oh, this one went somewhere, just not anywhere you wanted it to go.
You can say “billionaires harm society, literally”. That’s a literal statement that is true.
You can say “billionaires benefit society, literally”. Thats a literal statement that is untrue.
You can say “billionaires are human, literally”, so long as you are talking about individuals, and not corporate entities.
You can say “billionaires are steaming piles of shit, figuratively”. They are not literally turds emitting water vapor. That metaphor is quite apt, but not literally true.
Likewise, they are not masses of mutated cells. That metaphor is also apt, bit is not literally true.
You can say “teratomas are cancer, literally”. You can’t say “this argument is literal cancer”. It is figurative cancer, not literal.
