As much as it is a network it still needs to be sustained. That is why you notice that the the fees are kind of high. It also depends on the fluctuations which are not that often but do occur. Then again it is true that bitcoin mining is not for everyone. If you want to mine bitcoins and get a lot out of it then you need to have a lot of resources at hand.  the fees are just ok just that you are looking at with the wrong perspective and once you get the right perspective you will be able to get what I mean. You can still have a lot of bitcoin by starting off as a miner. It is all about how you mine.
