@ Geezer: I agree about what you say about experienced capitalists. And your rules of thumb, I'll accept, probably 'work' for that reason. But as you say, they are a starting point - but surely they vary with the cost of 'labor' and other factors, and anyway the maximation of profit isn't the only goal? People I know who have run small businesses often become attached to the product of their businesses, the way they choose to produce it, as well as the profit they make from it (which does, you'll agree, have to do with the difference between profit and wages, not just something that comes after wages are paid) and to the environment (including the social environment, which obviously involves employees, as well as customers) they have created, and I wouldn't be too interested in frequenting a business where this was not the case. Seems to me this probably applies to most or all of the small Western-run places in Kunming that I know about, which do not strike me as mere 'money machines'.
@ Peter: I don't think I know of any Westerners here who feel seriously desperate, except perhaps when they first arrive and are unfamiliar with a lot of things here.

@ Geezer: don't understand your last post.
Perhaps the rule of thumb you mentioned makes sense, I wouldn't know, but if it does, why does it?

I appreciate Xiefei's comments and, since I started this thread, I'd like to point out that I did not mean to imply that anybody in particular is into serious greed. I have no idea what the margins might be - I meant what I said: "...merely an impression." I don't think we're producing dollar millionaires, and I hope not.

Nice to own, rather than nice to live in, seems to defeat the purpose of an apartment.

Location of The Park is on the courtyard of then Buddhist temple (now full of shops for tourists) on the island in the middle of Cuihu (see listing). I don't know how to join the wechat group. Notification of meetings happens on this thread, and is also usually entered on the calendar for the day.
