I think a lot good things are being said here. And Envato should care about this, and will most likely not as normally when these things reach the forums there is really pretty much a decision already made. In this case by the tone of the text it sure looks that way.
I am from Portugal where you can definitely live with about 1200$ p/month but I live in Austria where with that money you will pretty much struggle (a Lot!). In some countries like Australia like already said you would be on the street. Literally because not even the rent you would be able to pay.
That being said the major problem that this tries to solve is there and I think everyone can acknowledge that there are really complex themes and really simple themes right now with the same pricing, and that is not fair as well. But giving the authors complete control over pricing does not solve this at all, there will still be inconsistencies in regards to the work that put into the item and the pricing.
We will have items that have tons of work for really low and high prices, items that have very little work into them with very high and low prices as well. Mostly low prices really, but there will be a lot of inconsistency because its all very subjective and completely dependent on the author’s context. Where he lives, where’ is at in his career/life, partnership, not partnership etc etc etc…
Envato should invest a little bit more in reviewing what items really have in them, how much work was put up in it. Is it really unique in terms of the creative process? Does it have a lot of variations or whatever? And price items accordingly. Its not as scalable as what there is now, and what will come (so this will most likely be completely disregarded) but it would make for a more stable and reliable marketplace.
And for buyers this is a huge win. Because buyers don’t know what is in the theme until they actually buy it. And most times this is still a big surprise, most of the times not a good one as well.
