coal is that expensive partly due to indirect and direct taxes that are cumbersome in Poland for any business
Exactly. And yet it's the mining that struggles and other business keep working.
Of course if you are economically very much to the right you may believe that simply removing taxes would fix the problem. Doesn't change the fact that in the current system they are money pit and a burden.
Btw- in Russia they are taxed as well for sure yet they manage to get it much cheaper.
To me the mining as it is is useful only as a back up/emergency/ safety net kind of thing. Generally Poland should look how to nove away from it.
