The Maximum City; Or Is it???

Hey, Back after a short break. This one comes from Mumbai. The break was for settling down here.
Well, the first couple of days were great and then came the rains, which people welcomed with great joy after the scorching heat that had gripped the city. But their happiness soon turned sour!! The Greater Mumbai region has the higest population for any metropolis in India. As I write this i got an article whose link i am pasting here. It says Delhi urban agglomeration with has the highest population in India.

Coming to the topic, the BMC (Brihan Mumbai Corporation) , the wealthiest corporation in the country promises a clean and a flood free city every year. But every time the same ting keeps on repeating. Accepted, it rains very heavily here and every place cannot be covered, but what I am talking about is the fact that at most of the places the basics are where the problem lies. Roads with potholes , the first couple of days of the 2 month long monsoon saw many areas under water; very slow infrastructure building...the Santacruz flyover for example has been taking ages. Spoke to some people and they tell me it takes 3 years to build a flyover in Mumbai while in Delhi the time is around 1.5 years!! May be its because of the political pressure. But I find beacuse of the aggressive nature of the populace of Delhi, things get done there, while here its taken for granted and called the "Spirit of Mumbai" that inspite of the rains people go along with their daily lives!!
Why this step motherly treatment to this city? Everyone wants to come to Mumbai and make it big.Mumbai has given so much to this country. 50-60% of the total tax collected in India comes from this place. Its hight time that the central govt cracks the whip as it did in Delhi and solve this once city of dreams' problems. Because a strong Mumbai is needed for a strong India!!
