At first I thought transport is not that essential. If there were no buses, the most you can't go to work or you just stay at home and don't go anywhere.
But, on further thought, it could be much worse. Take the worst scenario. All transport drivers (bus, rail and taxi) go on strike. Life will come to a stand-still. This will affect other essential services. Workers like nurses and fire-fighters cannot report for work. Tourists who want to return home cannot go to the airport.
I am one of those who support bus fare increase. I think it it reasonable. Of course most people will say no. Nobody will say yes to any increase unless it benefits them. I guess most MPs will speak against it in parliament even if they think it is necessary. I suppose they cannot be seen as unsympathetic or do not want to be accused of profit-minded.
