"Exploitation is wrong by anyone, Communism is exploitation of the strong by the weak"
-- Pierre-Joseph Proudhon
"Capitalism was supposed to destroy the middle class, leaving a tiny clique of oligarchs ruling over a vast proletariat. In fact, capitalism has enlarged the bourgeoisie wherever it has been practised. Capitalism was supposed to lower living standards for the majority. In fact, the world is wealthier than would have been conceivable 150 years ago. The whole market system was supposed to be on its last legs when Marx and Engels were writing. In fact, it was entering a golden age, hugely benefiting the poorest. As the economist Joseph Schumpeter put it, the princess was always able to wear silk stockings, but it took capitalism to bring them within reach of the shopgirl."
-- Daniel Hannan
"Some claim that resources in a planned economy need be allocated only to production and distribution. With no need for profits or for advertising, costs will be cheaper. In practice, however, profit spurs people to seek out market opportunities. They are constantly looking for needs that can be satisfied, or efficiencies which can be made, and to the gains which these can bring. This is why the market economies are so flexible and adaptable at bringing people the goods they want, by contrast with the sluggishness and unresponsiveness which characterized the socialist economies, and which still characterizes state industries."
"Essential services are too important to leave to the private sector, and have to be done by the state. The assumption here is that state provision somehow guarantees that essential services will be delivered."
"The market system does not depend on people ‘working hard’, but on their making the things that other people desire – and in ways that conflict least with the desires of others. Its rewards are not a ‘just’ reward for effort or personal merit, and do not even reflect the size of the investment that is made – people sometimes hit on highly successful products that cost them very little time and money to develop. The market rewards only the value to others of what each individual produces, whether it came about by luck, good judgement, or hard work. Some thinkers, such as Karl Marx, adopted a ‘labour theory of value’ that suggested that the value of a product was determined by the labour invested in it. (He used this to justify the expropriation of capitalists, who do not seem to put much physical labour into the goods they produce.) In reply, Böhm-Bawerk and other Austrians argue that this is completely confused. Value is not a quality that exists in a good, or a quality that producers can put into it. Producers can work hard, and invest a large amount of time and effort, and yet create a product that nobody wants. Value is what customers or consumers think of the product. Prices are not a measure of how much time and effort has gone into a product. Quite the contrary: prices inform producers how much time and effort is worth putting into a product. Production does not determine prices: prices motivate producers"
"Exchange therefore benefits people just as much as production does – something that socialists, with their focus on production, often overlook."
Communism treats people as though they're machines with no free will.
Government does not accomplish, they decomplish
If you don't use the invisible hand, you must use the red hand of Lenin/Stalin
Basically this is the attempt to bring equality to cultures.
