Yes, of course! No one expects a bunch of western weebs to save Japan's demographics. Obviously, Japan will have to change their insular culture and work ethics, if they attempt to deal with the problem by significantly increasing immigration. Yet there are many western countries where the issue is how to prevent all the people attempting to get in from doing so.
The people America is trying to prevent from coming in are largely low skill, low education, generally do not speak the language, and so on. These people are no more a solution than our idealistic weebs. In most cases, they're rather worse off since weebs at least tend to have language and other skills, but are trying to move to a place that doesn't exist.
US also put a lot of roadblocks in a way of highly skilled immigration. For example, check the waiting time of Indian engineers to obtain Green card.

Not sure I agree with this assessment. Unskilled immigrants tend to be over-represented on hard low-paying jobs, both in EU and US. Someone has to build, pave roads, cook, deliver, tend of elderly, etc.
