The sad consequences of the combination of a number of causes:

1) ridiculous rat race to the bottom in pricing by customers always going for the cheapest trucking supplier

2) inter-European right of free movement and work - which means that in Germany, there are truck drivers at domestic minimum wage (9.60€/h) and truck drivers from e.g. Romania for a less than a quarter of that - 2€/h (https://www.handelsblatt.com/unternehmen/handel-konsumgueter...).

3) a serious lack of unionization among truck drivers - hard to contact people when they are constantly on the road

Right now, people are actually looking at the plights of truck drivers because of the crunch, but I can guarantee you nothing much will change and especially no one will bat an eye at the situation once the crunch is over.
