This link does not provide evidence that it would prevent broker from lending out your shares. This “lock” is only placed internally in the broker’s internal system, there is nothing preventing the broker from lending out your share anyway. If they can’t get your shares back in time before your order triggers then they would just compensate you.
Depending on the country and on the broker, investors who own the stock can profit substantially from lending out their holdings to short sellers. Unless of course you use one of those cheapest brokers or an index fund to “lower” your transaction costs - then the broker or the fund manager will lend out the stock which you own and pocket the entire profit.
So the response to the argument: investors support the company, short sellers support the investors.
As a Russian programmer living in the west, I know of at least one strong reason:
Harsh climate, forces you to stay more in-door during the winter and autumn. This naturally pushes people to be more involved with computers. I am sure anyone who live in the area with strong winters can emphasize.
I disagree with the answers that about good schooling or teachers. Teachers and professors are strongly underpaid, bribery in universities exists, IT teachers in pre-university levels frequently can’t even touch type, rely on outdated curriculum, use old textbooks that break apart. Certainly I learnt nothing from IT lessons in school except how to do arithmetic on binary and other things of little practical use (and also boring.)
And about the answer that good grades are emphasized. A-students who dedicate most of the time to studying can be bullied like in the west. Being socially outgoing is definitely more valued in school, just like in the west.
You also have to look at the following dynamic: immigration system in the west creates a situation where if an immigrant is fired from his job, he will lose his visa. Which is very hard to get in the first place. And obviously western people don’t _need_ to be to good programmers: all they need to be is to be good managers, who can exploit the opportunity of getting cheap talent to work for you.
