From Simon Kuznets, who invented GDP as a concept:

Economic welfare cannot be adequately measured unless the personal distribution of income is known. And no income measurement undertakes to estimate the reverse side of income, that is, the intensity and unpleasantness of effort going into the earning of income. The welfare of a nation can, therefore, scarcely be inferred from a measurement of national income as defined above.

If he can question it, then we certainly should instead of just accepting it because “we’ve always done it this way”.
