This is with reference to bus fares in the city, which have skyrocketed in the past few months. The bus I used to travel in has raised its fare from Rs 10 to Rs 16. Considering a two-way journey, this signifies an increase of Rs 12 daily and Rs 360 per month. This is especially hard on low-income people like housemaids and labourers, majority of whom travel by public transport and so lose considerable money to bus fares. Perhaps government should subsidize intra-city travel by busses. -HAMNA HANIF, Karachi, via e-mail, August 22.
