Socialism is wonderful idea that you can get something for nothing and that is how it has always been sold to the weak minded.
Socialism is a form of collectivism. Collectivism is group identity. Socialism uses central planners to determine what the collective needs. It is a one size fits all solution.
It is the idea of everyone pulling together to make a better world. The problem is how it is always been, always is and always will be implemented.
In order to make this better world the individual must be stripped of all his or her rights. That way the central planners can work unhampered by any laws or constitutions that protect individual rights.
This includes 4 inalienable rights that are mentioned in our Declaration of Independence and in the 14th amendment to the Constitution. Those are the right to life, liberty, property and the pursuit of happiness.
Under socialism all 4 of those inalienable rights are taken from you. You no longer have the right to life, liberty, the pursuit of happiness and property. Why is that a problem? Because those 4 rights form the foundation upon which freedom is built. Without those 4 fundamental rights there is no freedom.
Without freedom NONE of those wonderful promises that socialism makes can be a reality.
Considering how the worst kind of people are always attracted to power and control and that socialism is the ultimate power and control grab over the lives of the people, then take a wild guess at who A) is pushing socialism and B) who will be the central planners or ruling elites or the oligarchy?
This is why socialists always try to tell you that real socialism has never been tried. Um... yes it has. This is exactly what socialism is. Even with the best of intentions when you take complete power and control away from the individual and give it to the collective (who are governed by the oligarchy) then this is what happens.
Basically put, if you want another Adolf Hitler, then socialism is how you get another Adolf Hitler.
People hold Hitler up as the worst human but Mao Tse Tung murdered far more people than Hitler. Joseph Stalin murdered more people than Hitler.
All in all socialism is directly responsible for the genocide of between 100 and 150 million people. I have been told by some socialists that those numbers are inflated. Oh really? Does some number under 100 million people still justify socialism?
