The economy/jobs don't usually reward things that everyone can easily do, and everyone they know can do magic.  Like maybe their skills would be marketable in the muggle world, but that doesn't earn you any wizard money.

If they were standout talents who were creating new spells and mystical objects they could probably make some coin.

True except there's an exchange rate between muggle and wizard currencies.

Just earn money in the muggle world with some on the sly magic. Use a third party to exchange the moolah.

Boom, rich wizard/witch.
