Yes, it is profitable to work in Western economies, but current political situation often makes it outright impossible, and back in the days when it was possible it wasn’t super common - mostly due to language barrier (most Russians are not fluent in any foreign language, including English) and the culture that pressures people to stay in. Phrases like “you’re good where you’re born” are common sayings here.

High-profile specialists, though, are the first to leave for sure, in search of higher wages, a safer/better place to be, etc. etc.

Also now that a lot of male population was under the threat of mobilization, a lot of young people have fled the country to where they could, taking their families with them.

There was a thing with freelance work on international platforms that brought good money without having to leave the country, but soon after freelance economy started truly booming, Russia started the war which ended up in main payment channels being closed - and barely anyone outside IT specialists offers serious freelance work paid in crypto or by other means.
