It's a very complicated question. I've been pondering over it for a long time. But, you know, it has turned out be that there's no way out.
Let's just imagine that we refused to to use them. What is gonna happen? Will everybody be satisfied then? I guess not. Why? Because everything has its price. Yeah, sounds lousy but it's true. I have something, for example, then in some time I realize that I don't need it anymore. How am I supposed to get rid of it? Just throw it away? No, of course, I can't. Exchange? But how? How can we exchange stuff without comparison? So, this is the price.
We can't also get stuff for free. (By the way, what about stores?). If we did, who would manufacture it?
"Get paid to pay"!
And, finally, don't you feel that smell? Yeah, it smells of communism. My forefathers were trying to build it in my country for about 80 years - now USSR is gone. They didn't want to use money but actually money were using them for all that time.
Sorry for mistakes.
