to the hard working farmers who oppose this:
in the current system someone can (discreetly) buy credits and instantly trump all your hard "labor". don't you hate that? with the tax system you will still be rich as long as you work hard fairly and honestly. cred sellers will no longer be able to ruin your hard work. they cannot store credits for long periods of time because it will disappear.
what will they end up selling? alien armor. HOWEVER, that means they will have to farm. credit farmers dont farm. they buy creds from players and sell higher, and buy old accounts with farmed ingots creds. currently they have huge stores of credits that was obtained easily. farming items will be extremely hard work and a waste of effort. they will not make a profit.
it will take weeks to obtain a few pieces of alien armor, while 10 billion credits can be sold under 30 minutes. (a seller personally told me this)
in the complex credit selling cycle, the credit ends back in the hands of the cred seller, by being both buyer and seller.
the tax system will heavily combat them and benefit honest hardworking grinders.
