This is supposed to be Thailand, not some Reincarnation of London, New York, Paris or Sydney. Many people come on holiday to experience a change of culture. Street food and markets have been cleared from many areas because some bright spark decided they were an eyesore. A real off put, is to find double pricing in many places. Haggling a price with the seller, used to be all part of the experience, it still happens but not so much now. Treating foreigners as cash cows, doesn't help as you only get one chance to make a first impression. The world is a much smaller place than it used to be 20/30 years ago and as such, Thailand is exposed to the worlds press. Tidy up and improve things by all means, but keep it Thai. The biggest improvement that this country can and should make, are to the driving standards. In so many cases you put you life on the line travelling by bus, van or taxi, because the driver in high on booze or drugs. Why? Because he is on a time schedule to make as many runs as possible. Stupid is as stupid does and this is the only country I know that teaches stupid.
