I meant outside real economy. We can say that income distribution does not matter, within real economy, and call all income there earned.

No, income distribution absolutely does matter. What doesn't matter is whether that income distribution arises from, say, high wages and high personal taxes, low wages and high corporate taxes; private pensions or discriminatory public pensions; and so on.

Once you have the income distribution, you have the income distribution. To low order, its origin story isn't all that interesting for the purpose of economic forecasting.
