Hmmmmmmm....
Build up TV appearances: keeps all folks in television employed. Say... oh... 75,000 jobs.
Fly everywhere possible: keeps Airplane parts/mechanics/terminals all working. Say... oh... 10,000 jobs.
Throw money at the infrastructure: save masons/ road builders/ waterworks/ crushed stone/ steel/ heavy equipment/ etc STILL employed... but... uhmmmm... not necessarily creating 'new' jobs unless they need more help. Say... oh... 60,000 jobs. And, since one man works and 4 others watch, then it is surely 240,000 jobs....
I'll give the floor to anyone else who can help get to 600,000...
