You can learn from history by reading "Legislature Speeds Dewey's Bills To Raise Realty Taxes and Fares" (Back In The Day Long Island Star Journal March 17, 1953), as the same issues for transit riders apply today.
Future fare increases are inevitable due to inflation complimented by increasing costs of labor, power, fuel, supplies and materials necessary to run any transit system. MTA services are still one of the best bargains in town.
Since the 1950's, the average cost of riding either the bus, subway or commuter rail has gone up at a lower rate than either the consumer price index or inflation. Prior to the MetroCard which affords a free transfer between bus and subway, riders had to pay two full fares.
Purchasing either a weekly or monthly pass further reduces the cost per ride. Thousands of employers offer transit checks, which pays even more of your costs. Better to pay the piper now then later.
