The bad points are that multinationals, with their "different" ways of doing things can neglect the local customs and habits of doing things, resulting in "cultural erosion". But it's rare (basically) that a company can change a country. Competition is good for the consumer, and we are consumers. In most cases it stimulates local companies to improve the services they offer to consumers. The market decides. The problem is when market forces (consumer choice) are overridden by government protection. This happens when government tries to secure votes by "protecting" the people, but they're usually trying to shore up votes. So you'll see cycles: election far away - no problem with foreign cash coming in to the country. Election close: they'll push a more domestic agenda (they need the votes and foreigners - even just a company - can't vote.) So yes, a necessary "evil", but remember they hire and train local folk in the process. Without it there would be no foreign trade, no global economy. North Korea is a great example of government protection (at the extreme). Not a place that values consumer choice. Hope that helps.
