Interesting that they didn't declare what would happen to those who refuse to accept the offer.

There are other ways to make them cough up the money, but it'll probably piss off the exiles even more and no idea if Singapore will bend like Switzerland did to the US. Besides, if the government took over those companies it wouldn't close down overnight. It'll be a slow decay unless they find someone capable to take over. I'm sure there would be less-rich Indonesians interested in taking over but that'll spook investors.

In the long run, yes, the tycoons do lose since Indonesia's economy is booming. They can be either a part of it or settle for what they have.
