The people rule and prosper during movements towards reestablishing the Constitution
Your can't look to Ancient Rome and compare it to Western society, because all of the faults began with socialism. We have slavery today when the people are to assume they have a right to talent and skill of another laborer. Slavery does have a meaning, you're just misconstruing it to further your gospel of wealth.
Social Darwinism is survival of the fittest and why shouldn't the poor be at a disadvantage? Future generations would be happier if their ancestors weren't lazy, unproductive and unskilled hands. Overpopulation and famine wouldn't be a problem if people took responsibility.
Be careful when using that word "ancient."
As Aristotle wasn't introduced to Western Europe until the 13th century ACE, the full significance of Socrates' political insight wasn't realized until the 18th century ACE. Look, before the time of this reintroduction of Zenith philosophy, the only schools were Christian. After Aristotle's works were introduced into Western Europe during the Crusades by Arab Moor philosophers, Western Europe had to build Universities of higher learning to unravel their mysteries.
Socialism started with Hegel who argued that people could not be free without owning property. Marx and others expounded on this idea later on.
Challenging Hegel that people need to own property to be free were the early Christians after the time of Christ. Because a lot of these Christians were slaves who did not own property, they met to worship God under overturned fishing vessels. They exercized the New Covenet to "Love thy neighbor as thyself" by loving their brothers or sisters sitting next to them as their Spirtual ground.
This small cult became known as "The Way" until it grew so great that it threatened the rule of Emperor Constantine. It was then that Constantine created a new Christian religion on material grounds so that he wouldn't have to convert to the Spiritual ground made up of poor people. After this new material religion was created, the poor Christians obeying the New Covenet on Spiritual grounds had to convert to the new religion set up on material grounds.
As a result of this forceful conversion to a religion set up on material grounds, the prior Christians lost their Spiritual freedom. Now they couldn't preach the Gospel nor spread the Word of God by the oral tradition (the scriptures were set to memory).
Ultimately the bondage to religion became so great that early Christians fell under a ritual of legal precedents set up by the Pope and the Vatican while the bible wasn't allowed to be read by them unless it had been written in the Latin. The Latin version was a poor translation because it was done so second hand not by experts desiring to worship God but by novists desiring to rule the people.
The use of the derogatory word "Slave" originated from how Europeans viewed the lowly Slavs of Eastern Europe. Anyone who appeared similar to the pitiful Slav later on was called the derogatory name of a "slave" by them.
If it were decided that it is best to let the poor starve to death, it would not be a decision based on the science of evolution. The word "fittest" doesn't mean either strong or week. Sometimes the freak, the weak or the small are the only animals that can survive a change in the environment. Much the way the small mammals survived to over take the dinosaurs during a cataclysm that was believed to have happened some 60 million years ago.
