Chocolate covered strawberries.

I'm not really sure how to make the biggest difference.
Boycotting specific industries for exploiting people by hoarding their profit doesn't always help.
It just reduces the capital, and therefore reduces the minimal percentage the workers end up receiving because "well, hey, we can't afford to pay a decent living because this season didn't make us rich enough for our own jet."

But refusing to purchase products because the industry, the capitalist structure, and the exploitation of people  is unacceptable could make a difference if enough were demanding a change, and the industry suffered a big enough blow that they have to listen.

"If enough," though.
How do we awaken the people around us?
How do we make the biggest impact?
