So taxation and adjustments around that will need to be looked at. I agree that a sales tax makes more sense than a 'pre-sales tax' - I expect eventually we'll have a mix of the two the tax as the Union's cut and an adjustable fixed fee (say 0-500UC per item) as a territory owner's listing tax.
Regarding the contracts - I get what people are saying (and I certainly agree that mining should net more profit than trash collection). My view of the solo-play options is that they should provide a 'living-wage' as it were, balanced around being able to pay insurance, rent, food etc. That said I agree that there should be some progression, some of which will need to be thought out.
30mins to produce just over 2,000UC doesn't seem that bad for a solo-player tbh, ofc couldn't tell you what a Peacekeeper is going for on the markets atm since my pc in in the repair shop and my laptop has less processing power than my toaster. In regards to long term plans if we have an average of 2,000UC for every 30mins of contract work and assume that of the average 7hrs a week a person plays 2 are spent in MR doing 'dailies' they'd make around 8,000UC. If the costs to this player who plays for 2hrs a week are around 6,000UC he's 'progressing' at 2,000UC a week, which puts him in the underclass. If engaging in faction play for those 2hrs nets him 10,000UC and his costs remain the same he doubles his weekly bank account gain which encourages faction play...
The problem with a living wage is that it adjust as the market adjust aslong as it does end up like before the eco fix EVE or FOTD FoM where the market was just trashed and prices where high. This requires you to adjust the contracts as the markets adjust. On the offset 2000 uc in the current market nets you what 1 gun and maybe 2 mags of ammo good luck.
