Under my idea, spending on lobbying would affect the equation zero. Contribute to charity (which is still a wide range, Dolly Parton has done so much good through her works through self-initiated foundation that I would suggest she is the gold standard).

Give to existing charity. Create your own foundation (although our government should be watching like a hawk in such a scenario to make sure you're not just funneling money back to yourself).

There might be use in considering corporations "people". But that analogy only holds so far before it becomes worse than the disease it's trying to contain.
