كل شخص يبحث عن مصلحته

هي مبدأ الغابة، وعكس مبدأ التضحية من أجل الآخرين

It's every man for himself.

something that you say which means that everyone in a particular situation is trying to do what is best for themselves and no one is trying to help anyone else It might be a civilized place to shop at other times but come the January sales, it's every man for himself.
