You quote Einstein but he was a democratic socialist who would have strongly disapproved of your praise of an arch-warmonger such as Reagan. Reagan gave huge tax cuts to the rich while massively boosting military expenditure and withdrew legislative shackles upon Wall Street that have created so much suffering and chaos across the world.
In 1949 Einstein wrote an article, 'Why Socialism' you would do well to read it. He hated capitalism and wanted a democratic socialist world:
"I am convinced there is only one way to eliminate these grave evils, namely through the establishment of a socialist economy, accompanied by an educational system which would be oriented toward social goals. In such an economy, the means of production are owned by society itself and are utilized in a planned fashion. A planned economy, which adjusts production to the needs of the community, would distribute the work to be done among all those able to work and would guarantee a livelihood to every man, woman, and child. The education of the individual, in addition to promoting his own innate abilities, would attempt to develop in him a sense of responsibility for his fellow-men in place of the glorification of power and success in our present society."
