Tell me: which "human rights NGO" scripted that once again? Everyone (and her sister) are in this business well knowing what it's all about. They're in it for the money. If they weren't aware of what the reality of it is, they'd be working as cleaning women or factory workers, and making a bare fraction of what they're making in this "harsh reality" in Pattaya, and lots of other places in the country.
Everything else: delivered as ordered. A transformation from a idyllic village to a metropolitan hotspot is never painless, anywhere, and takes a lot of urban planning and inter-departemental communication (so that roads aren't cut open for long stretches during high season, among many other things). Where's city hall and/or trafic police when baht taxis can't be bothered to pull left, out of the trafic, to let cars pass while loading/unloading passengers? Or pick-ups double parking in neuralgic spots? I could go on for hours. But hey, we have vulnerable individuals to worry about, so the rest isn't really a biggie, is it now?
