Whataboutism or whataboutery (as in "what about…?") denotes in a pejorative sense a procedure in which a critical question or argument is not answered or discussed, but retorted with a critical counter-question which expresses a counter-accusation. From a logical and argumentative point of view it is considered a variant of the Tu-quoque pattern (Latin 'you too', term for a counter-accusation), which is a subtype of the Ad-hominem argument.
In case you’re serious, it’s because the costs outweigh the benefits. Specifically, the benefits would accrue to everyone, while the costs are borne by the individuals doing the “fighting.” This is known as the free rider problem. Realistically, there’s not much an individual can do to change an entire society. Moving to better circumstances, however, is a realistic alternative.
