I think that more effective than voting with your wallet is voting in your elections and communicating with your politicians. Even voting with your wallet by donating to support political action.

Collective action is more effective when it's done via law because that removes the incentive to defect for personal gain. It means that people not paying attention aren't accidentally contributing to immoral causes.

In a case like this collective action means things like putting tarrifs on goods from China, so that their workforce isn't important, and banning exports to China, so that their market isn't important. More direct laws like "no censoring what China wants you to censor" are problematic because it's hard to detect in most cases, and it often violates freedom of speech.

And yes, I'm suggesting a very painful thing to do economically.
