Why did western nations want to contain the spread of communism?

We wanted to keep our freedom, communism is not the type of government we wanted. We believe in a different political system

^^^^ Bringforth the LOLCATS, the below is an alternative answer.

Or Becuz the RICH doesnt like it, becuz if communism is in its full swing, people cannot be ripped off by the ruling elites. (take this 2008 financial crisis as a reference). What will happen next? The ruling elites will divert their attention to take ownership of the real physical economy. Capitism dictates that the fittest win all, and one day every thing will be owned by a single entity, a new astriocacy class will rise and 99% of the population will be enslaved by the 1%. This plan is always in motion without you knowing it, throw a frog into boiling water and it will jump out but if u throw a frog into cool water and rise the temperature slowly and gradually, it will not jump out. That means u all are adapting to the surrounding and think everything is ok. Capitism only give the FITTEST to own thing, don't assume u r fit. When the day come. The first step is that MNC will takeover all the SME pre-2008 (if u are observant enough to realize, shops in the corner were whacked out of existence by 7-11 and Walmart). Next those MNC will be taken over by the ELILTES (mark my Word in 2009 to 2011). With their resources, they will destroy every startup companies and competitors, making sure of their dominance. By then, its clear you can never own a business so u can only be a working class, but the worst fact is all the business belong to a same boss, so if he offer u usd$1 / week , u either take it or leave it, u cannot quit and join another boss, there isn't any other boss around anymore. Then they will sell commodities at a high cost, u either buy it or leave it, there isn't another seller.

U will become a peon as u are born destinated to be. How great is it? I bet 99% are looking to this blessed simple life. It's a blessing for u, u will work 18 hrs a day and given 3 meals, u have no worries or troubles where to party, don't have to make option becuz someone is making for you. I think this is ideal for the 99% of the population. It will be a utopia + nirvana + paradise.

By then, if u are one that doesnt like a simple life, u may pray u can time travel and begged ur grandparent to support communism. But i for one will prefer the current state not becuz i like a simple life but becuz i happen to be one of that 1%. Juz focus on playing the role WE planned for you. LOL
