if you look at the inflation data carefully, it tells you something else - it's less that food is too expensive (it's not that bad, relatively speaking) and it's more that wages are too low. employers have done the usual scam job on us, in hiking prices faster than wages. so, real wages have fallen relative to inflation, and that's really what the issue is.
we don't solve these problems with stupid commissions on competition. that's retarded.
we solve these problems by organizing, marching and striking for higher pay.
