At very least they both share immense responsibility for causing individual harm. Sure the government may start a war, but that war can’t happen without bombs and bullets, and in America at least those factories aren’t run by the government. There is an intermediate step oftentimes, but I don’t think that necessarily disconnects companies from responsibility.
If you work at a guided bomb factory you may not be the person dropping it, but you are responsible for the destruction it causes in a small way.
Also, if global warming kills us all then it is likely that the oil companies bear some responsibility for it right?
Government sucks - I agree with that statement, but we shouldn’t act like corporations are appreciably less responsible.
Building a mega corporation without big government/s I would argue is basically impossible. And local level governance is more likely and potent without big government. Again though, all of that is quite hard to achieve / see how to achieve when people with existing power enjoy the status quo control more of the levers than the masses, including the ones used to influence the masses.
If nobody were able to socialise the cost of going in a foreign country and killing people, there would be no war.
If the government didn't steal my money against my will on threat of incarceration, there is no way in hell I'd spend my money on bullets to kill someone's son in another country.
In the 20th century governments slaughtered wholesale around 100 million of their own citizens (China, Russia, Cambodia), let alone those of other countries they killed in war. There's no measure by which the market comes anywhere near that amount of murder.
The small one will redistribute my money where I live at least.
Besides, there is an alternative model where there are competing groups of people and I can pick the best among them based on price and services.
In the absence of government, what's stopping these groups from simply joining forces into a cartel, getting some armed thugs and making you an offer you can't refuse? History suggests that to be a far more likely scenario. Oligarchy, rather than competition, is the natural state of capitalism.
