If you're going to continue to peddle this I guess someone has to shoot it down.
'Take' has many definitions, including the #1 definition of take as a verb, which is how the article uses it:
http://www.thefreedictionary.com/take
v. 'To acquire possession'
Now lets look at the word 'national income':
http://www.thefreedictionary.com/national+income
n. The total net value of all goods and services produced within a nation over a specified period of time, representing the sum of wages, profits, rents, interest, and pension payments to residents of the nation.
Nowhere in that definition is 'national income' defined as being the property of the nation as a whole as opposed to private property, and nowhere in the verb 'take' is such a word implying any impropriety.
It is perfectly reasonable to speak of the nation of the United States as collectively having an income, much as it has a national product. Are you against the term GNP/GDP as it implies that a nation's production can be measured collectively? These statements make no judgment as to who owns such production other than that it is created by residents of the state. This is how GNP/GDP can be used to measure North Korea's production as well as the United States'.
You basically flipped out because you didn't know the definition of words.
