A better analogy for us is “pulling the ladder up behind them”
We have the resources for everyone to “get out of the bucket”. We have a ladder to get everyone up. Certain class traitors will get up to the top and then pull the ladder up behind them (or put the lid on as you say).
But really, as you say, there’s a force outside the bucket pushing the crabs back in because it plans to eat them and extract from them. So the crabs need to help each other up the ladder AND defeat the outside force that contains them. Also they are human beings not crabs. This is why analogies don’t really make sense past a certain point, and ideological models are just that.
