Just like the Jews every other person who had to engage in forced labor by the Germans has to be compensated regulated under the German constitution.
After losing the war the Germans lost everything. In order to revaluate Germany as an object for investment, trying to identify the points of breach of contract, the state got kept intact as an industrial nation, with the said constitution implemented.
The plan was as following: the Germans were supposed to keep their state officials in check proving that the people weren't at fault. This didn't happen. Today Germany again has forced labor and attacks other countries.
Why would anyone in the world want to pay for that?
It's similar to offering fair trade products where in fact you deliver something not fair trade at all. Why would anyone else now want to sell real fair trade when the Germans get away with the trash they sell?
The Germans had been given the chance to reward performance in order to create a world wide legal bases to operate upon, because in order to create a legal bases you either have to reward performance or punish criminality.
In case you still want to pay for German products you will simply steal out of your own pocket. Because they only got left a country under the condition they will keep their promises so they won't suddenly start shooting at you.
It's kind of like the Germans already saw that coming, that they will have to pay the replacement Jews compensation as well, and trying to keep their robbed goods they will choose war. Maybe they will bow try to keep their state officials in check before becoming more poor than Lithuania.
The only reason why Germans are even left shoes is their promise to realize the constitution.
You might have bought it but Germans didn't lose the war out of pity or because they were the philanthropists they portray themselves as.
