I agree with scaeagles, a boycott is unlikely to have any real effect simply because economic boycotts very rarely do (though someone writing on Twitter "I think we should all also boycott Arizona Iced Tea because it is the drink of fascists" is hardly an organized boycott (even if the guy wasn't
joking) though it made for amusing headlines").
Missed a page of discussion. Yes, I'm willing to let people work for $2 an hour picking vegetables, but that is simply because I don't particularly support minimum wage laws. That said, while it is the law, I am willing to pay the rates for vegetables such laws would indicate. That said (again), over time paying legal wages for farm workers wouldn't necessarily increase prices by multiples because there are plenty of forms of automation that could be developed easily enough -- in fact many of them were invented decades ago -- that would be cheaper than legal labor but are more expensive that black market labor. So in the end we'd end up in many cases with
nobody picking (or rather one guy driving a big machine) the vegetables if current labor law was effectively enforced.
