Capitalism is central planning - for profit - by banks and corporate CEOs instead of in the public interest. A free market is only possible if no organized firms or agents exist in a market economy, and then that would last for exactly one generation since the winners of the competition then grow bigger and start to plan (vertical integration) the economy. In their interests, instead of in everyone's.
So a planned economy is the only kind that really exists. The only issue is who gets to do the planning and in whose interests. I prefer planning that is "of the people, by the people, for the people".
Take the recent issue over Yahoo. Marissa Mayer, one of the most brilliant scientists in the world, ground floor at the start of Google, expert on Artificial Intelligence, becomes CEO of Yahoo 3 years ago. She buys 25 other companies in acquisitions (central planning). Why? She wants to have a long-range strategy, something that Google and Amazon are also successful with (central planning), developing long-term technological breakthroughs, innovations of engineering (self-driving cars, robots, AI, rockets to space, etc.) that can revolutionize life on earth, while making profits, NOT now, but in the future (central planning).
All of the acquired companies were "brain" - they were companies of software writers, engineers, technicians, biotech experts, etc. that she is hoping over the long-haul will work together to innovate in ways they could not have in their individual firms that were specialized on just one or another technology (central planning by Yahoo).
BUT, a hedge fund called Starboard has purchased a large amount of Yahoo shares (central planning) and demands, in the business press and at shareholders' meetings that since profits (1.2 billion) are the same as 3 years ago, that Yahoo instead sell off its entire core business (central planning) and instead increase its large share (20 or 30% I can't remember which) (central planning) of Alibaba, which is the giant Chinese retailer - larger than Amazon - by using the revenue from selling Yahoo itself (central planning) to buy more shares in Alibaba which it thinks will increase the stock price more than what Mayer is doing (central planning).
So, we have three options here - not let's even say four: 1) central planning by finance on Wall St. in this case hedge funds, but also banks, pension funds, investment banks, central banks like the Fed; 2) central planning through vertical integration by industrial or high tech corporations - in this case by CEO Mayer; 3) central planning by a democratic public or by stakeholders - recognizing that corporations are social, not private, entities, collective, not private property, and so democratizing the companies and having planning be made democratically by employees, managers (elected), consumers, government, communities, shareholders, suppliers, and others effected by the company's activities) or by public ownership and democratic control by employees, stakeholders and government; or 4) central planning by a Chinese bureaucracy - the Communist Party and Chinese company management.
Before you answer that 4) above is incapable of competing, or is inefficient, consider that 100 of the Fortune 500 companies are Chinese State-Owned Enterprises (SOEs). So they must be doing something right. Yet that is my least favorite of the four options, with finance tied with it for first. So that leaves central planning by industrial managers of firms or by public officials with mandates from democratic stakeholders. I prefer the latter to the former, but both to the first two.
Central planning is ubiquitous dude. There is no market anything in any of the example above of Starboard and Yahoo and Alibaba, except for the stock price, itself open to manipulation since most purchasers of stock and of bonds are institutional (hedge funds, central banks etc., investment firms) anyway and not individuals. The market is a myth, it does not exist. Get over it. Maybe it existed briefly between 1776 and 1840, but it hasn't existed since and that was in a pioneer, underdeveloped country and did not end well (Civil War). Since the first railroads got built, there has been no market.
So who do you want to plan? For what and in whose interests? That is the only question.
