but the problem is that we need to do both. we're not blameless, and throwing our hands up and doing nothing because they won't either is incredibly not helpful.
just like when voting, individual action may feel pointless and hard, but it's still necessary. we can still do things and make choices, but everyone is just giving up now because of this feeling...
of course corporations are polluting more, but so are we, and we can still force change through consumer action. just like conservatives are dumb for bitching about companies "catering to the left" when it's actually just the same things they always have and always will do: cater to the average. if more of us would stop and think "huh, this product uses less packaging, maybe that should be a factor in my purchasing decision."these companies would start using less packaging. but no, most people just open something over packaged, and either don't notice, or shake their heads for a moment and comment on the plastic waste before buying the same thing again next time...
we can't be defeated by the inaction of others. if we do, then even their action won't be meaningful if/when it comes. it's going to take more than just one side...
what you are doing is called "Individualization of Responsibility" and it is a successfull tactic used by fossil-fuel-lobbies to shift blame away from themselves.
edit: don't get me wrong. I don't think you are doing this intentionally. But I do think, that by accident you are being useful to fossil-fuel companies
