he'll be fine. when trump kills fema there will be massive job creation from every state having to duplicate capability, he can do that. alternatively, international aid as a job is largely project management and by its nature ends up being a lot to do with exports. the us isn't going to be able to export much in future as trump moves to make it completely uncompetitive (inevitable effect of tariff sickness) but there may still be some jobs left in that area.   international aid in the 21st century is generally just state aid for domestic industries you can get past the wto. massive job losses incoming.
