The communist experiment failed, because Communism is based on the uprooting, control and destruction of basic human rights and relationships. Marx makes it very clear that part of the Communist agenda is the breakup, forcible or otherwise, of the family. It is also based squarely on subverting the basic right of personal property, from which all other property rights are derived.Communism bases itself on fundamental lies and moral abuses and the abrogation of very basic human relationships and rights. Theft, home invasion, lying, torture, starvation, and historical revisionism are all hard wired into Communism.
Rome was able to gain its empire in large part by extending some form of citizenship to many of the people it conquered. Military expansion drove economic development, bringing enslaved people and loot back to Rome, which in turn transformed the city of Rome and Roman culture.
