No, this is not really a normal work culture in the US. It is definitely something that is prevalent in the startup space, but really that has a lot more to do with the low barrier to entry rather than the country they are located in. There are companies that will let you work yourself to death all over the world. At a normal established company, these sorts of expectations would lead to these same sorts of failures, in which case you actually don't typically fail upwards. Management this bad doesn't typically stay management for that long at profitable companies because they introduce an enormous amount of risk.
