I looked up Bloomberg's bio and saw he's a Jew. Why do so many Jewish politicians want gun control? It would seem they had learned 80 years ago.
SHORT ANSWER
Because gun control is good for the Jews in the USA and gun control will make it easier to do things to you that you might object to.
LONG ANSWER
Thomas Sowell dances around the JQ in some of his books. He writes tangentially and/or to the superset, rather than to the specific case of diaspora Jews. His superset term is, "middleman minority."
Middleman minorities have similar characteristics:
0. Live in a polity as a minority.
1. Mildly greater g/intelligence than majority ethnic group (less than one std dev).
2. Extremely high in-group preference (nepotism, et al) and out-group antipathy
3. Actively seek to infiltrate ruling class and influential cultural/economic sectors
4. Ally with majority-group ruling class in opposition to majority-group middle/lower classes.
Sowell does mention Jews, but spends more of his time on overseas Chinese and Indians (Chinese NOT living in mainland China & Indians NOT living in the subcontinent), especially when discussion middleman minority behavior harmful to the host majority(1) .
One of those actions is siding with the ruling class majority and enhancing its power by various means. To include disarming majority middle and lower classes. This increases the power of the ruling class and diminishes the power of middle/lower class members of the ethnic majority(2).
In short, gun control reduces the threat from middle/lower classes of the majority ethnic group when the middle/lower classes figure out that the ruling class (of which the Jews seek and succeed in joining) is shafting them, good and hard.
(1) Sowell has protective coloring, but no amount of coloring will protect a man from speaking too much truth on this topic.
