Considering the struggles between labor and capital, in the light of technology, and analyzing technological developments through income distribution, makes it possible to observe the socio- economic structure of capitalism that is based on inequality. Therefore, the main motivation of the paper is to investigate effects of technological progress on the functional distribution of income using quantile regression analysis in the period from 1980 to 2021 in Turkish economy. The findings of the analysis reveal that both intra- labor and intra-capital income distribution deteriorate due to technological development, however, as the share of labor from national income deteriorates much more, the functional income distribution changes in favor of capital. In addition, the results point out that the national income share of the qualified labor force increases with the technological development, the unqualified labor force remains idle, this idle labor force is used by the capitalist for surplus value, and hence intra-labor income inequalities accelerate. On the other hand, it is also determined that the investments made in technology in order to be victorious from the competitive race driven by capitalism lead to the concentration of capital and in this context, it is observed that the income inequality among the capital class increases. In general, it can be said that the capital class gets richer and the labor class gets poorer with the technological progress.
