The amount of money they have is really not a huge factor. What benefit will they bring? Billionaires are fine, but how much of that will stay in Canada?
Are they going to start a company and hire locals? No, they already have this in place somewhere other than Canada, that's why they are rich
Are they going to spend a lot of it in Canada? Maybe, and just a little more than Joe Average
Are they going to blend in? Probably not, these people tend to be older, family already done yaddayaddayadda
The 25-35 year olds have job skills we need adding to the standard of living. They will raise kids, pay taxes (hopefully) contribute to society. I don't know what the ratio is between a millionaire, billionaire, and average person but for me, I'd rather have 100 people spread across the board (not just doctors and lawyers) than 1 millionaire. This has nothing to do with someone being Chinese even though the vast majority of the applicants are from China. The good news is that most of them won't be sponging off of social welfare. However, why do we need a 60 year old rich guy instead of a guy who is 30 and his wife and kids. Over the course of their lives, the 30 year old guy will leave behind much more money in Canada than the rich older guy
