The secret weapon against WalMart is unionisation. If at least one employee in every WalMart across the country joins a union, every one of those WalMarts will be shut down. That has been WalMart's consistent reaction to employees joining a union.
Not remotely close to reality, but OK. There's a lot more involved than just that to even get a retail outlet unionized.
And FWIW, unionization in retail is a terrible idea. Been through it on both sides as a worker and a manager.
