I think you are wrong. Then again, I am Canadian.
Why is being Canadian important? That is because of the way the CDN government does Retirement letters,. They were able to keep down the monthly payment system.
I don't have t have 800 k in the bank here
The retirement visa is a simple thing once you get the hang of it and understand what they want. I have been here since 2010 and have always been on retirement, and really, there have been no changes. There is no need for border runs or flying out of the country.
With the online system for 90 day even that is a simple few clicks to get done.
The annual report is simple and quick
If they want to make other types of visas available, that is OK, but as history has shown, people will abuse them (working without a permit) and start to pull them back again. It reminds me of my dad he used to give me all sorts of leeway until i stepped over the line and then is was start from scratch and go at it again. LOL
