allowed to simply pursue their goals without interference
And that is crux of the problem brother, why do you think they werent allowed to pursue their goals? Because someone else wanted power, and thus they will continually enact the best form of Government that allows them to keep control of their power. As I stated before, the ideal of Communism is great I dont disagree with the basic principles and I believe that if Christ were to rule the world it will be a Communistic Ideal. However I live in reality, I see History and I know Human Sin and in reality, seeing History and understanding the evilness of Sin and the fact its not ever going away until Christ comes back, then I know that Communism will forever be one of if not the most Evil of all type of Societies.
Capitalism in the real world is a better system period, I believe the rights of the individual outweigh the desires of the collective and just on that point alone Capitalism is a much much better system of Government. I can stop there, I personally dont need to go any further, my rights as a human being ought to be above anything initiated by the State period. I do not trust the State ever, and I do not want the State to decide what it is I ought to do or tell me that the need of it the State is above my personal rights and desires. Such as I should not be forced to give up a kidney because the State has deemed that someone more important is in need of it. I am using this as an extreme example but the ideal behind it still stands. My personal rights ought to always trump the States, but in Communism the State ALWAYS trumps the rights of the individual.
Economically, there is a reason why the West lead the World into the Modern Age with all the luxuries and conveniences we have today, like running water for basically free, electricity, toilets, ample food, heat, cars, and pretty much everything you can see in your house right now, and that is because of Capitalism. Communism didnt produce these things in their Societies and if you look at almost every Communistic Society millions upon millions upon millions of their citizens dont have basic conveniences. In the West do we still many people that dont have access to these things? Of course its not a perfect system but I will tell you what, as long as you are able bodied (and even the disabled have MUCH better lives here) then you have an infinitely higher chance of upward mobility to achieve anything you desire in a Capitalistic Society as opposed to a Communistic one.
I saw your argument against the fact that a form of Greed is what motors the Capitalistic Society, but I say Greed is the extreme form of desire of that which is necessary for life. In my view it is simply the desire of that which is necessary for life that is the true motivator in the Capitalistic Society. I need a house, running water, electricity, a toilet and food, so what can I DO so that I can attain these things? There the motivation and the answer is PRODUCE something of value for someone else. This basic ideal is WONDERFUL for everyone involved. A man working for what he needs producing something that benefits someone else, this is backbone of a PRODUCTIVE Society. And the LESS interference from the STATE the better the Society works.
Communism is literally the exact opposite, it is the STATE in full control, dictating what the needs of other WILL BE, not necessarily what they HAPPEN TO BE, and then mandating what one must do, with no care about your personal desire. The State can say well you only need 1 meal a day and well thats all you get, while you must work at this factory you hate for 16 hours because that is what is needed of you. Its a demotivational system all together. There is never anything new produced for all mankinds benefit in the Communistic Model in REALITY. (Yes on paper it would be) because I cant decide I want to make a smartphone and then everyone else cant look at my new smartphone and say yes that benefits me what can I do to attain it, and then they go do something to get it ect.
Even in our Capitalistic Society we can see the ill effects of Communistic ideals in the Modern Welfare State, where many able bodied people refuse to go work, why? Because the State provides for them and thus they begin to drain the Society and contribute nothing of value back into the Society for what it is they have taken. Why should they contribute? They dont need to.
Communism in the real world is the worst, again I will take this flawed Capitalistic Society any day, plus simply the fact that the Elites themselves are pushing Communism in every single freaking college in America and Europe tells me its something I never ever will desire to have. If the Elite endorse it, well its for their own benefit!!!
