I guess you are experiencing that "cultural disconnection". Sorry, that's my fault. Please allow me to clarify my (cultural-affected) point-of-view:

I've paid for my entire education for years. In Brazil, that's the most-probable alternative to make you way up. There is the public (free) education system, but it is really bad at the lower levels (children) and highly restricted at the upper levels (there are vacancy for just 0.5% of the studants at the public universities).

Paid education is a heavy-weight corportation-sized investment at Brazil, and we don't have any help from government or corportations.

Now you have a bigger picture, hope you can understand my question: why shall I put my money on something others will use to make money without paying me for it?

In other words: when you put your money at the bank, the bank uses it to make more money. At the end of the investment time, you receive your money back, and an aditional ammount, in payment for the use of your money. What makes my employer think that it can use my knowledge (a.k.a. "money", as I "buy" it with education and books) to make money and don't give me anything in exchange?

Please don't confuse this with the work I already sells to my employee, and that is fairly paid. That "extra" money built on my expenses is what I don't see as fair.
