First off, I really really fail to see where you are going with this. Your quotes don't seem to take any kind of logical process, they seem to be nothing more then random quotes. I also think you are misunderstanding some of them.
I am contrasting some of them with the way popular Keynesianists like Krugman seem to think it is.
Those points are:
1. Governments are supposed to pay off their debts during years of good economic growth so that they can defecit spend in years that need government stimulus.
2. Keynesianism is not a form of socialism or Marxism. Krugman, for example, doesnt seem to give a shit about any differences between the three approaches.
3. While Keynes recognized the faults of capitalism, he saw nothing worthy of replacing it and so wanted to make it more efficient and more humane via government leadership and validation of the market and marlet practices. Krugman and the neoKeynesianists of our time seem to think capitalism is not the best model but Fabian soicialism is instead.
4. Keynes, being a Brit, simply assumed the government had the right to intervene into the markets in any way it wanted because in that country all things ultimately belong to her majesty's government. For American neoKeynesianists this is problematic since we do not have that as the foundation to our laws as the Tenth Amendment specifically limits the scope of Federal authority though Keynesianists have been telling everyone that the 10th is an anachronism that needs to be ignored for the last 80 years or longer.
As to the accuracy of the quotes being from Keynes, take it up with Wkiquotes. They seem to have more resources than you do and they apparently have confidence these quotes are from Keynes.
