Yes, even without the state. At any rate, smooth-running councils don’t have to be quite as comprehensive as the Economic and Social Council. There are examples in Japan and Chile. There was one in Korea for a while, but it doesn’t function now as it used to. It was a very different time when it was established: a protectionist economy, clear economic conditions, and a negligible number of global players. It would be impossible to find the same conditions in today’s globalized world, with so many international players and so much mobile capital. Smooth running councils tend to have very specific and measurable outputs. Sectoral councils are actually quite widespread in the world and are frequently hailed for their efficacy. There are some in Chile and there were some under Lula in Brazil, and they all worked well. They gathered the best players in the sector in question, were sufficiently comprehensive, and focused on issues very specific to the sector. There are sectoral councils and committees within TOBB, but its own structure is problematic.
In short, there are countless organizations worldwide where the private sector is represented as broadly as possible alongside many other segments of civil society; these groups even include academics and other expert players outside labor and business. When these organizations say something, the public has to take notice; they’re real players in that market.
In Turkey, communication among business, academics and opinion leaders is very limited by comparison.
