How can any legislation possibly benefit everybody? Surely, the purpose of legislation is to restrict the activities of some, to benefit another class of people.
You completely misapprehend the purpose of laws if you feel they should ever benefit everybody.
For example, the law against rape, section 1 of the Sexual Offences Act 2003 (Labour legislation) does not benefit rapists.
Do you want rapists to benefit from our laws?
Do you think Labour legislation should have taken the interests of rapists into account when drafting its legislation?
Were the last Labour government not sufficiently pro-rapist for you?
