Not even close; here&#x27;s an accounting I did covering just Western Europe just for this century as of a little over 2 years ago: <a href="https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=4970408" rel="nofollow">https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=4970408</a> and the same with some discussion: <a href="https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=5070201" rel="nofollow">https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=5070201</a><p>Add e.g. Canada and &quot;[it&#x27;s] overwhelmingly a US problem&quot; is even less true.
