Oh please, you are trying to turn a discussion about one absolute principle in regards not to economics in any specific system, but the simple principle that jobs are created by demands for goods and services in any system for the creation of jobs. Period.
My point is that you don't even grasp the principles that you think you are advocating.
I detest Paul Krugman. There are many ultra-left economists that I have no issue with, but Krugman is a virus. The issue is that Krugman is an advocate of the democratic party. He presents partisan goals and dresses them in psuedo-economic terms. Then people like you, with zero grasp of economics, read his idiocy and think it's legitimate.
IF you want to be a Keynesian, then pick up a copy of "The General Theory Of Employment, Interest, And Money"

I'll warn you in advance, that if you do, you'll discover just how full of shit Krugman is, what a fraud he is.
My biggest problem with the leftists in the forum who claim to be advocating Keynesian economics is that you don't! You think you do, but you've never been exposed to Lord Keynes and imagine that the fraudulent idiocy you read from Krugman is legitimate economic theory - it isn't, Krugman is no more legitimate than a medium or an astrologer, he is a fraud. He has an agenda and he has no integrity, the mixture is the utter shit that you and rdean spout off about here.
You have yet to name a single job that has been created without actual or anticipated demand. Not one, in how many days to think about it? And for giving a challenge for someone to come up with that example, I become a partisan hack? Instead of you or anyone else coming up with an example, some are actually reinforcing and agreeing with the principle of demand creating jobs without even understanding that they are doing so. The i phone is a great example. The poster admits that the investors would not have invested if they didn't believe they could promote a demand for the product, hence, anticipated demand. Yet, the poster thinks this example is a good one to make his case and the subject poster of the thread agrees. They are making the case against themselves, and you, the self acknowledged economics genius can't comprehend a basic principle of job creation and a basic principle taught to elementary school children. An action causes and creates reaction. Demand is the action that creates a job, which is the reaction.
Where you imagine that you have presented some great "gotcha" conundrum, all you have really done is exemplify your ignorance of the subject.
There was no investment in the iPhone. Apple hired Steve Jobs and gave him an R&D budget, with the faith that he would direct the company toward breakthroughs. No investor was asked to back the iPhone, they merely had stock in Apple.
Jobs had the vision to realize that with proper execution and with the legendary marketing, he could create demand for the iPhone. The supply of the product with proper marketing created the demand, this is how markets work.
Your biggest issue here isn't whether Keynes was right or wrong, it's that you have no grasp at all of what markets are or how they function. You lack the foundational knowledge needed to even have an opinion.
