Socialism is a system based on the idea that everyone should be taken care of. It is the very basis of the movement that everyone deserves human rights. Socialists do not always support the true idea of socialism and become corrupted, that is true. But the very idea of socialism/communism is built upon the idea that everyone deserves to be taken care of. And that is different than most any other political ideology which would focus on supremacy of people based on class, race, gender etc.
A lot of socialist dictatorships had arise in the past century. They were the most brutal and careless about human rights.
But go to read Karl Mark, does he say that dictatorship is the way to go? Does he say that a state should enslave dissidents into gulags?
Socialism just advocates the equal distribution of goods, that's all. If someone tells you that we can't equally distribute the good otherwise we'll end up being in a dictatorship, he's either a billionaire or an ignorant. In the past socialism has always been defamed in a dishonest way by the media, specially in western countries.
Socialism upholds basic human rights by insuring that everyone's basic needs are met through equal distribution of government controlled products. Unlike a capitalistic society, which focuses much more on what people want to attain, but don't necessarily need and in that way is a very individualistic, self preserving concept, a socialistic society keeps the focus on the well being and benefits of society as a whole by insuring that as many people as possible receive food, shelter, clothing, and the benefits of government social programs.
Socialism is a system which decides what people need, and decides which people need it. The problem is that this may conflict with the individual's judgments of their needs. In socialism, the government controls the police, the courts, the schools, the health care, disability, welfare, etc. The individual's perceived needs represent a cost to the government. The government acts to manage (eliminate) that cost, which focuses the power of the police, the courts, etc, onto the individual. So, when the individual disagrees with the System on whether he or she is in need, and how that need should be met, the government can respond with overwhelming power. Consider the experiences of Justina Pelletier, Sophia Mirza, Karina Hansen, Isaiah Rider and others. When it comes to socialism, follow the money!
No, socialism does not uphold all important human rights. In creating a System to provide people with what they need, the System must decide what people need (instead of the individual deciding). Then, it identifies people who have unmet needs (even if the individual doesn't agree they need this "help"). In a socialist system, where the government controls the law enforcement system, the justice system, health care, disability and welfare systems, it relies on all of those powers to force its "help" on people who do not want it, or to deny "help" to people who actually need it. Socialism attaches a social "cost" to the individual, which the government has an incentive to use its powers to address, making the individual into a a cost to be cut. The process of cutting that cost, will focus the full force of the government -- police, courts, hospitals, schools, etc. -- onto the individual. And, that is a recipe for human rights violations. Consider the plights of Isaiah Rider, Ashya KIng, Justina Pelletier and Sophia MIrza -- all victims of socialist policies.
Socialism is not founded on a philosophy of natural rights, but on a theory of social betterment. It is not based on an understanding of the natural condition of man and his inherent nature, but on a utopian concept which defines an ideal good. It does not leave to the individual the determination of what constitutes the pursuit of happiness, but decides and dictates this to all members of society. This is a fundamental difference, based on the abstract idealism of socialist theory, as opposed to the realistic view of existence posed by natural rights. (It is treated more fully under the essay on Natural Rights.) While recognizing that all men are created equal in their entitlement to political rights, natural rights also grants to men the freedom to discover their own potential and to make of their life what they will. Natural rights do not attempt to compensate a person for his natural shortcomings, nor diminish the rewards to a person for his natural abilities.
Socialism as well as any other form of government is run by political leaders who abuse authority to their own advantage. Under socialism there is no incentive for the people to be productive as they expect the government to supply everything for their survival. This is evidenced by our socialized system today. Most people on the welfare system (socialized dependence) will not look for any type of productive existence. All become the slaves of the government leadership. While they live in luxury the rest of the people live a life of poverty.
No, socialism does not uphold all of the important human rights, because socialism can only spread misery. The government cannot create wealth, it can only redistribute what already exists. Socialism tries to make everyone equal, but all it does is create disincentives for hard work that result in lowering everyone's standard of living.
