vote with one's feet

Meanings

1. To express one's preferences through one's actions, by voluntarily participating in or withdrawing from an activity, group, or process; especially, by physical migration to leave a situation one does not like, or to move to a situation one regards as more beneficial.

Etymology

Probably based on the practice of pedibus in sententiam ire in the Roman Senate, but the phrase in its modern sense was popularized by Lenin, through whom it gained some currency in left-wing parlance in various languages. It became more widely known when Western journalists and politicians started using it, not without mockery, in reference to those individuals who fled Communist East Germany towards the West between 1945 and the erection of the Berlin Wall in 1961.
