If "demand" creates jobs, then rain creates umbrellas.
What a stupid response. Why would anyone need umbrellas if there were no rain?
So you actually think rain creates umbrellas?
Yes, most of them, as someone pointed out, some are made as sun umbrellas, but the vast majority are made because people demand something to prevent the rain from falling on their heads other than a hat or newspaper or magazine (which gets destroyed after one use).
