You will find that sticking to your principles of paying fairly will be difficult, because Singapore is quickly becoming one of the most expensive cities to live in.

What you save in taxes, you will pay back many folds in rental and transportation costs. If you have never been to Singapore, you will not be able to imagine how much it costs to own a car in Singapore. Most expensive in the world, by far.

And because of the ease of hiring foreigners, you will find that there will be plenty of cheap rails programmers available... may not be the type you want, but you will find pressure from elsewhere questioning why you overpay your staff when cheaper ones are available.

And for a population conditioned to ill treatment, you will find that you will not be able to change the cynical culture overnight.

Lastly, if your competition is also based in Singapore, then you will be competiting with assholes with asshole level productivity and cost structures. Over the long term, you will win. But over the short term, you will be choked to death by the assholes who can promise more and cost less.
