The global economy is 10 times the size of the global money supply. So, everything runs on credit, except The Underground. In our world, cash is king. So, if you are going to make a party, have someone who understands finances make the budget. Charge the cover price you need to charge so that everyone gets taken care of. Don't compete with other events. Remember that the music-makers are our technoshamans, they modulate the trance energy, they must be supported, for without them, the beating pulse of trance is nought.
It's not right and it is not fair and it is not sustainable when people get something without reciprocating. Long term, it does not add up: pain and hardship hit the very shamans we are honor-bound to protect. We see this problem on a global scale (I sometimes think I hear Gaia weeping), but we don't fix it in our own scene. And if we can't get sustainable in a cash economy, how on earth (pardon the pun) will we unwind all that global credit and balance things out on a global scale?
We are the canaries in the coal mine, friends. Credit is dried up. Now it gets ugly. Or beautiful. (Anyone else read Jared Diamond's "Collapse"?)
