The fees are high because miners probably overwhelm the network to collect higher fees for transactions. I do not understand why developers do not come with any fix that will solve this problem.

This is not true, the fees on ethereum chain is still stable at this moment. It looks like he was missing something about this. The solution will be fully implemented in the next update and you must watch what will be implemented after serenity update.
So here we go again? The last time that we heard about newbies complaining about ETH gas fees is during cryptokitties rise 2018 if I'm not mistaken. So to the OP, you really need to learn how to set up gas fees similar to bitcoin. There could be updates coming, but everyone should understand the economics of crypto mining, sometimes the gas fees will really shoot off because there are a lot of transactions happening. But most of the time it will flatten out and be back to normal.
