I have some knowledge about Philosophy now

But it is not appreciated by others and seems useless to them.
I must learn Finance. A lot of people need my advice in it. I can earn money from it.

No one wants to learn about Philosophy. I can talk to noone about it. But I could talk to anyone about Finance and they will love it.

It is rare to find someone love Philosophy but it is easy to find someone love to be taught about Finance, about investing money.

Philosophy is pretty Idealism but money is materialism.
