The verdict is in, and contrary to what socialists say, capitalism, with all its warts, is the preferred economic system to bring the masses out of poverty and to make them productive citizens in our country and in countries around the world. Remember this: Capitalism rewards merit, socialism rewards mediocrity.
The motivation for innovation is driven by the individual participation of wealth. The primary driver is - this may sound amazing to some - asset preservation and the secondary driver is asset growth (accumulation).
Within socialist societies and, by the way, also communities like the Kibbutz, general individual wealth is not sought at all, and in extreme cases (communism) it is even abolished (except for the ruling class... what a miracle). Therefore, the motivation to be innovative and therefore more competitive is far less present than in capitalistic or economic liberal societies. This leads, e.g. also in the Kibbutz, to the fact that the individuals contribute less to the general work effort, since one has nothing from it. On the contrary, so-called "heroes of labor" (who increased the expected productivity through their zeal for work) were generally hated in the former GDR.
