Quote - All vendors have the same motivation. Dollars. They make what sells.
No need to look furhter then that.

Is it the market that drives the vendors?
Or are the vendors driving the market?

None of the aove.

The "Dollars" make the market grow the way it does.

I agree to an extent, but then all that I've said before also plays a part. Only a few vendors can actually make a living at this anyway, and look who the most earning vendors are. Those that make props. If I was only in it for the money, that's what I'd be doing.
