I actually voted for "Leave it as it is", because it's actually the first time on LS-RP when I enjoy a "pretty realistic economy system".
Even though, I would suggest adding Happy Hours, when the paycheck would be increased by 1.75x or 2x when there's more than X players (based on the current playerbase I would say more than 60 online).
//edit
Also payments from jobs would be increased during Happy Hours.
