Nothing happened to "Russians in the West". There are literally millions of such, some quite wealthy, untouched.

Instead "very specific Russians" who had their wealth tied to the Russian state, were targetted.

This is a very important difference, completely followed a legal and standard procedures, was not arbitrary or decided upon by a dictator, or single person.

So no, "rich Chinese people" are not "dumbasses". And most are not "rich", but what the West would describe as "moderately wealthy".

M, not B wealth.
