For clarity, I am an advocate of intelligently regulated capitalism with moderate social safety nets.
That said, your essay is riddled with naive and poorly made arguments, you set up a false dichotamy between socialist and capitalist countries—you seem to imply that only socialist-leaning countries can achieve economic and educational success.
You frame a slew of economic and social problems in the U.S. as being solely caused by capitalism, but you conveniently overlook the complex and multifaceted nature of these issues and the significant role of policy decisions.
Finally, China is an example of State Capitalism. However, you attrbute China's achievements to socialist policies without recognizing the important role of market reforms and how capitalism has been the engine of its growth.
