Lifestyles cover the day-to-day expenses of living. Basic food, rent, utilities, Matrix access, etc. are all covered by Lifestyle. Here's a quick and dirty description.
Streets: Literally, on the streets. Living in a cardboard box, eating out of the garbage, and freezing in the winter. - Free
Squatter: You live in a run-down squatter building probably shared by other squatters. You eat low-grade nutri-soy and yeast, adding flavors with an eyedropper. It sucks. - 500¥/month
Low: You live in a crappy apartment whose key feature is that the door locks. Payments to the local street gang are part of the lifestyle cost. Power and water are available during assigned rationing periods. Factory workers, petty crooks, and folks stuck in a rut tend to have this lifestyle. - 2,000¥/month
Middle: You have a nice apartment or condo with some comfort. The auto-cook has a full suite of flavors and you occasionally get natural food. This is the lifestyle for ordinary wage-slaves or reasonably successful criminals. - 5,000¥/month
High: You have a roomy house or condo, good food, and technology that makes life good. Your home is in a secure zone or protected by good bribes to the local police contractor. This is the life for the well-to-do on either side of the law. - 10,000¥/month
Luxury: Ha ha! Yeah, right! - 100,000¥/month
