REGULATION is what killed the private companies.

The cost of a system is paid for from the fare box, and from tax revenues. The government is free to increase either or both of these at will. A right balance must be struck.
LION Says: $3.00 Base Fare.

Multi Trip Tickets: 2 trip = $6.00; 10 trip = $25.00; 30 trip = $60.00; 60 trip = $110.00 (Thus a fare between $1.80 and $3.00 depending on how many you buy.)
Woah! Not everybody can afford that! Well, subsidized fares are available from Schools, Welfare Agencies, Senior Citizen Centers etc. Depending on the tax subsidy 30 trip tickets might cost between $25 and $50, however usage restrictions may also apply. School tickets might only be good between the student's home station and the student's school station [station defined as any conveyance entry within 1/2 mile of any given point], Senior tickets might only deduct a fare on the return trip, allowing a pass at the person's home station.
There are many ways to subsidize those in need while raising the fare for those who can afford it.

Unlimited Tickets are sold by the DAY. A day is deducted from the ticket on any day that the ticket is used. Days cost $12.00 each (4 trip basis). So a one day unlimited is $12.00; a 5 day unlimited is $50.00; and a 30 day unlimited is $200.00. There are no discounts on unlimited tickets.
