Well, in slavery you were working for someone. that someone can treat you in any way he/she wants. in communism, you work for an entire state or country. that country can't treat you in any way it wants, because it is obliged to give you something in equal terms with other people.
Instead of being a slave to one person or family, you're a slave to society.
I'll stick to owning my own body, thank you.
The problem with communism is that it assumes the collective is always right. If you don't want to work for your community, or you want to do something they don't support, you're out of luck. That's why capitalism is so great, because it allows people to act on their own behalf. People in the minority can work for themselves, or choose whom they work for. People in the minority can make trades the majority of people are against, and still make a living satisfying other people who are in the minority.
Let's take a look at an odd real life example:
http://www.dailymail.co.uk/femail/article-2172650/How-woman-making-living-snuggling--60-hour-pay-hug-stranger.html
This woman makes a living hugging and cuddling with strangers. What would we do with her in a communist society? Would we allow her to make a living cuddling, or would we force her to become more productive?
Personally, I think it's absolutely ridiculous she can make so much money cuddling strangers. I feel she doesn't work nearly as hard as me, yet she gets paid far more! Perhaps, in a communist society, she can be forced to do a "real" job. But, that's what makes capitalism so beautiful! No matter how envious me or anyone else gets, she'll be allowed to work the way she wants to work! Nobody can stop her through jealousy. Nobody can stop her through envy. Nobody can stop her through disagreements of principle. I may not support what she does, but I thoroughly enjoy the fact that she's allowed to cuddle for a living. As long as her and her customers are happy, me and everyone else who disagrees with her practices can **** off. The only way she can't do her job in a truly free-market society is if the demand for her services go down too much.
Or, under communism, she can be allowed to cuddle strangers and get paid the same (whether we pay her in currency or not is irrelevant). The problem with this is that those of us who don't support her profession are being forced to take care of her. Why would I want to work for people who's business I don't support? Here's the wonderful thing about capitalism. I don't support what she does, so I don't have to spend a single dime on her! If someone thinks my profession is immoral, impractical, or inefficient, they don't have to support me. That's a wonderful thing!
Capitalism allows people to act according to demand. Communism doesn't. Communism acts off of what the majority of people want, and the minority are not allowed to do business with one another because they aren't allowed to act on their own behalf or the behalf of other specific people.
Actually, slaves are not seen at an equal terms with the "masters", but the people at a communist country have equality in every parts of life, including a same status with everyone in the country ( a politician is not higher than commoners )
As true as that is, communism is a different form of slavery. It's a form of slavery in which you must submit to the status quo. There is no such thing as becoming more successful. You do as the majority of people want you to do. You either aren't allowed to hug people for a living, or you're forced to work for people who hug people for a living if you don't support their business. Communists constantly spew "Workers should own their own labor", but they don't. The majority owns the labor. Under capitalism, labor is owned by one's self - and indirectly the person whom you work for.
I can not do my current job by myself, so I sell my labor to my boss. She owns my labor because I gave her consent. Under communism, the majority owns my labor, whether I want to work for myself or a particular person. I have no real say - except whether I want to work or starve, unless labor is forced.
this is where you are wrong. slavery was only justified with social discrimination and apartheid. it was NEVER justified with eliminating poverty, homeless people, or lack of food in the enslaved society. To an imperialistic country, do you think they care about the well being of the enslaved society? Try asking the Nazis, Napoleon, Cortez, Pizarro, Van de Bosch, Daendels or Thomas Raffles
So slavery is okay as long as slaves are treated as well as their masters?
Rather than forcing someone to work so you can house them the way you house yourself, why not give them the choice? Let the choose. Do you let them work for you, do you let them do what they want with their own life?
The thing about not being a communist is, I enjoy other people's success. Sure, there are a lot of people I believe don't deserve their money, but those people don't get rich off my dime - so it doesn't matter. Well, except for people payed through my tax dollars or companies I'm forced to buy from due to laws - but those are more socialist policies. Arguably, some of those are necessary - but that's a different debate for another time.
Also, the idea of equal reward for job input...it gives equal value to every job even when such equal value is truly not a thing. A basket weaver holds little to, say, a surgeon, yet they both must work in order to receive the same outcome.
This is a great point.
Communists believe all labor is equal. They don't ponder whether labor differs in, skill, stress, efficiency, or demand. All of these factors play a great role in determining value in the free market. Some jobs are easy, but there's a high demand, such as the woman who's job it is to cuddle. Some jobs are incredibly stressful, and requite a lot of skill, such as being a doctor. Some jobs are easy, such as working at retail stores or fast food restaurants.
