The US is targeted because it is large, generally wealthy (in the sense that a scammers will be willing to work for days to get an amount their victims will fall for), information about local communities is fully digitized and services (Walmart ir whatever) are fairly uniform, and - by far most importantly - culturally and linguistically dominant.

The scam calls mostly come out of the Philippines, India and Pakistan because they have high familiarity with US culture and millions of people with sufficient English fluency.

Almost none of the EU nations have more than two of these.

It is very easy to understand the problem if you pause and think about it for a short time.
