There are some oddities in how the equipment is priced. It's a percentage of your cost of living. That makes sense.
What doesn't is the cost of living is the same for all tech levels.
$600 a month for a caveman with a starting wealth of $250.
$600 a month for a Greek hoplite with a starting wealth of $500.
$600 a month for a cop in Atlanta in 2013 with a starting wealth of $20,000.
Rent sure has gotten cheaper since 10000 BC, ain't it?
