In the case of a public utility or not for profit exactly what I said is true.
"Because public services like healthcare, national defense, and education are rarely sold at a market price, Statistics Canada measures their output by calculating the cost to produce them. Therefore, the value of government output is deemed to be exactly equal to the total cost of the wages paid to public servants plus the cost of intermediate inputs."
So wages in such cases directly increase the GDP. If you pay a nurse or a police officer $50 per hour then for that hour the GDP goes up by $50
In the case where a corporation distributes profits it absolutely is relevant. You made the statement that the corporation is retaining the profits and that's not accurate. Dividends are akin to repayment of a loan. They are cost of doing business.
My statement in the original post could only be true if all costs are derived from labor.
Sure. In such a case GDP and income would be equal pre-tax.
Misunderstanding there I think, I was referring to Hoekstra, the reply is meant to be a reply directly to him about wanting American booze back on Canadian shelves not you. Sorry for the confusion, my bad
