It is not her personal wealth to start with. It is the taxpayer's money. The European Union has already agreed to provide some 20 billion to Turkey, so that they could take care of the immigrants. In addition to this they are spending a similar amount to take care of the immigrants inside the EU. She is wasting the taxpayer's money. The Saudis and the Americans must be made to pay, as they are the main players behind the Syrian civil war.
one of the reasons for tax money spending is to handle these big things that is too expensive for few people alone. compromises are necessity, naturally. spending a few billion euros to save a few million people in need is reasonable imo.
Germany is not "saving" millions of people. These people were living comfortably in Turkey. On the other hand, Merkel has caused thousands of deaths by drowning, by encouraging these immigrants to cross the Mediterranean.
the idee that refugees were "living comfortably" in Turkey sounds only like more conspiracy talk to me.
but at least i can agree that Merkel's generosity has unfortunate side effects like encouraging dangerous journeys like you said.
