To make America great again, requires a fundamental change in philosophy (metaphysics: study of the universe, epistemology: study of knowledge and ethics: values/virtues).
Politics is a branch of ethics, it is the product of a philosophic system.
This is what has to change, from collectivism/pragmatism/progressive movement/statism/democracy (tyranny by the majority) to the philosophy of inner synarchy.
America today is the result of the catastrophic political decisions based on the philosophy of statism:
The trashing of the Constitution by Abraham Lincoln
The Sherman Antitrust Act
The unprecedented entry of the government in the fields of finance
The New Deal of the thirties
The pressure-group pragmatism of the political parties which demand controls (government intervention)
