On this agree with you, i have a friend whose cousin used to work for mc donald, couldn't believed how badly paid they pay their employees. When he told me how much i was shocked. Anyway today, capitalsm rules, so companies will always try to maximize their profits. The food there isnt really healthy either, so wont be missed that much.
However, Russia's actions are really childish. Carrying out a 'purge' against a private food chain is not really wise. Morever most of the employees are Russian and they sources their food locally. So its kind of a Russian company. Seems Putin is getting ahead of himself. He needs to come down to reality.
