Keynesian economics is a horrible system, but so far it works the best until we have another implemented
Keynesian economics is not science, it's just form of propaganda. You receive money from government to justify big government and call this economics, ecology etc.
So you mean the Keynesian economics is not exactly as what they said because they're under control of the goverment?
Well if your income are 100% depended on the government you wouldn't say anything to harm it. You don't bite the hand that feeds you. And that alone is enough to really be cautious about information coming from that source.
Also the only modern active alternative school is austrian and they are proven to predict things way better and they have a radically different approach(and the one that actually makes some logical sense).
These are unfair and incorrect views of the Keynesian economics.
Keynes pioneered the study of the economy as an aggregate. It also introduces the idea of disequilibrium and price stickiness, which are occurring themes if you conduct any serious macroeconomic analysis. He also introduced behavioral elements in his formal analysis e.g. money demand equation and term "Animal Spirit". He would have incorporated expectation but the mathematics at his time was not advanced enough to handle that.
The policy prescriptions from Keynes's theory are natural implications of his theory, which remains revolutionary even to this day. The great depression in the late 20s dealt a huge blow to the Austrian school as well as western capitalism in general. It beckoned a response outside the box and Keynes' demand management really was the answer until the 70s. You have to remember that even liberals in the west placed a lot of hope on Communism during the great depression, the vibe was certainly very different from now.
While it is unfortunate that Keynesian economic theories have been politicized to benefit the state power, it is also nature that for a long period of human history big states and institutions exist. The Austrian school was too ahead in its time and the technology was not there until more than a hundred years later. The free market is still an imperfect institution (as correctly realized by Keynes) that is not really free and transparent, central authority is needed to enforce property rights.
So contrary to what you have said, it is Keynesian economics that was radical to the traditional Austrian school. Hell, it is even radical in this day as the neo-liberalism (a politicized descendant of the Austrian School) took over the world from the 90s that led to the tremendous growth of wealth and income inequality.
Nah, that's not right. Keynes used to say in radio that people should buy more and not do any savings... becouse! He may be a great mind for this time but spend without without any concerns about future prices embased on government printing or debt is just creative accountability. I really would like to read your sources about Keynes being this true Keynes thoughts, could you plz share? Regardless of that, in true, learn macroeconomic is a process that shuld go through Keynes - his description of economic forces is truly remarcable and easy to understand.
Perhaps ppl should consider a little bit more of the government involment over the 29's. As Freedman says: when the government, by laws or incentives, creates a false price, the whole market act on falses premisses. For example: If a Government gives money to build roads, buildings and etcs, more students would seek to be engineers, becouse the market claim for them. By the time they get their degree if the roads/buildings policy stops there will be a lot for unemployed engenieers. They act on a false premisse and this 'bubble' of unemployment is more or less the same of 29's. Not saiyng that the free market does not have part on this. But plz consider the Govenrment more on this.
