Open yr own eys first before asking others to do so.
USR was a communist country and it had become super power under communism. The person sent in space was from Russia. Initially it progressed very fast. As I told u there r plus & minus points of communism. Capitalist countries started social welfare schemes, only after communism took shape. These were plus points of communism, which they copied. China also made much progress during Mao. They developed infrastructure, defence, literacy etc., which was much better that India. Mao solved the language problem by implementing one language and script in the country. China could implement one child norm since 1979, curbing population growth. Population growth in China is 0.6%, compared to world average of 1.2% and India's 1.6%. Though we hv only 2.4% of world's land, we hv 16% of its population and still growing fast. Cuba produces some of world's best boxers every few yrs, after some of them cross over to USA.
But there is a big minus in Communism, that is there is no competition as no one can hv private property.
U must learn to see both sides of a coin.
Biggest advantage of Capitalism is competitiveness. If there is no fair competition, it becomes a disadvantage for the society and on most occassions unfair means r adopted. Best example is the fight between Ambani brothers, accusing each other of malpractices. Corruption is more in Capitalism, which in Communism is curbed, as noone can hv any private property.
