“Our dependency makes slaves out of us, especially if this dependency is a dependency of our self esteem. If you need encouragement, pats on the back from everybody, then you make everybody your judge.”

I don't think dependency is the all inclusive measure of slavery the quote tries to paint.

I get it, but for me, the world is other people. I may not be dependent upon it but your encouragement empowers me, and mine empowers others. What makes this a wonderful world is all that good stuff other people do because they want to -- and I want to bring something to the party, too. I suppose you could say that the 'good world' is dependent upon it -- does that make us slaves to keep up our end?

If the prefix 'inter' is added to the word dependency in this quote then its true nonsense is revealed.

Its a 4 cuz there are other factors to consider: a big one: Owing money
