ELI5:How is it legal for clubs to require men to pay more than women to enter a club.

In california the supreme court ruled it unconstitutional so it isn't legal there.

In other states the courts have not found it unconstitutional, because (according to the courts) it wasn't a means to discourage men, but a means to increase the number of women attending, like seniors discounts, or student discounts.
