In the same boat

Everyone shares in the same misfortune or fortune. No one escapes the actions of what occurs. If it sinks all perish, if it floats all remain.
Most often heard is, "We're all in the same boat". It means they we all share fates. It is also meant to say that the bad intentions of a person or their desire to separate, or absolve themselves of bad circumstances will not work. They will be equally troubled.
