What are two beliefs of socialism?

I took Economics of Health-Care in college and one belief is that socialism is where that all residents take care of other residents. The fact is in a socialist economy you do have a National Health-Care plan and National services to serve it's residents. But, the fact remains that the payment of these services do in fact come from the citizens themselves. It should be common knowledge that all governments run off the taxpayers money. If you want National/Social services of any kind someone has to pay for it. Money doesn't "grow off of trees". There are some countries where the citizens only receive 40-50% of their paychecks to pay for these luxuries. The second would be that all Socialist countries are "Neutral" when it comes to areas of World Affairs of Defense. You will find that these countries that consider themselves "Neutral" or "Socialists" refrain from International Affairs of War, belong to the UN.
