That's the german position on this (only in german):
Just some infos....after stats from the german Chamber of Industry and Commerce (IHK) about 25.000 people are directly concerned by this border closing between Germany and Poland...commuters who live and work in both countries. This border region developed in the recent years to a "joint economic area".
Brandenburg and Saxony decided to support the commuters financially when they decide to stay on the german side of the border....there is criticism against the polish gov, it's said they "overshoot the mark"!
BTW, isn't there online teaching in Germany?
Till Corona we were a digital third world country....now home office and digital schooling has become a topic...maybe if the right consequences will be drawn we will now start to close the gap and invest more in such stuff...also online teaching. But right now it's not really an alternative...especially not long term and especially not for the poor families...not every kid has a computer with internet at home!
