On Financial Secretary John Tsang's claim that he is middle class: Law Hin Lau - If he claims he is also middle class, then the rest of Hong Kong wage earners are all below the poverty line. Patrick Siu - I can get his message: If you are neither super rich nor financially dependent then you're in the middle. More like useless rather than false information to me. Barry Yau - Before anyone criticises secretary Tsang's monthly salary, isn't that what many expatriate (read white) bankers and QCs make in a fortnight? Deb Lindsay - This comment is as off-target as his budget estimate (original forecast of a HK$3.4 billion deficit now revised to HK$64.9 billion surplus). How can you get it so wrong and still earn that kind of monthly salary? I'm in the wrong job! Ellen Oi Lun Cheung - What a humble guy, Mr John Tsang. President Obama 's base salary is US$400,000 a year. I would say Mr Tsang makes even more than the president of the United States. Cindy Cheung - He means he is in the middle - between Li Ka-shing and those who live in cage homes. On government plans for a new citywide clean-up campaign: Fayadi Limpid - "Clean Hong Kong" is a positive step in the right direction. What is wrong with having cleaner streets? Singapore, Seoul and Tokyo, Hong Kong's financial rivals in the region, all have cleaner streets. It would be better of course if HK can at least try to outdo them in cleanliness. Patrick Shu Wing Lee - Some back lanes are terribly dirty. Some popular shopping districts with many visitors are flooded with not only crowds but also litter along the side-walks too. Another "Clean Hong Kong" campaign is long overdue. On Beijing's air pollution problems: Marcus H. Langston - I love it that Beijing and its corrupt unelected few can't hide their dirty secret any more. Wendy Yap - I wonder how humans can live there.
