No, the onus should be on the law, because corporations will do nothing "for th greater good" if they're not forced to do so. The onus is on the individual to help other individuals around them that need it, and on the individual to petition their law makers to do what needs to be done.
Putting the onus on the corporations is the one thing that's guaranteed, with a long and storied proven track record, of not working.
