well, to be fair, there are a higher-than-average number of business owners on here, so they really might work for them
The police get paid by and do the bidding of the government. They work for the government.
While you can screech about the degree of overlap between government interests and big business interests, and it absolutely is something worth screeching about, acting as though they are one in the same is counterproductive to understanding either.
It is also worth noting that in some cases, government and business owners have diametrically opposed interests - namely governments can nationalize companies (and if I'm not mistaken, some governments, like the Nazis, did, or would use the threat of nationalization to make business owners do their bidding with no regard for the interest of the business owner)
