Yet another irrational diatribe from Mr Vegter, who has an excellent track record of trashing everything without offering solutions.

Yes, public transport world wide is subsidized, and should be. Left in private hands, with the objective of maximising profits, ticket prices will be too high for the daily travel the less privileged have to endure. Obviously.

To offer minibus taxis or even metered taxis as a cure is just daft, especially if you take their track record into account. 

Mexico has an excellent PT system in the form of minibuses, which are completely integrated with other systems. They stop at stops, obey road rules, and most importantly cannot exceed a speed of 60kph. They are privately owned. 

Metered taxis have a role to play too, but the role they play here is to launder money, along with their big brother, the minibuses. They are unregulated, unsafe, uninsured, and ironically, mostly unmetered.

Public transport is highly complex, and your story simplistic.
