>petitioning at multiple sources of the problem is often more effective at getting things done

Could you provide any sources for this? As it stands, I've seen zero tangible results regarding Amazon's ongoing unchecked growth, the prevailing lack of workplace standards in their warehouses or for delivery drivers, monopolistic practices, or any general "ethical" standing of the company.

Same goes for the US Government. Sure, you can vote for who you want and try to elect change, call your congress reps, and protest at the chambers, but it doesn't matter when they nothing gets done at the top level. Until there is an honest discussion had about immigration reform without a partisan spin put on everything, we won't get anywhere with ICE.
