Do not consider Collectivists as "sincere but deluded idealists". The proposal to enslave some men for the sake of others is not an ideal; brutality is not "idealistic," no matter what its purpose. Do not ever say that the desire to "do good" by force is a good motive. Neither power-lust nor stupidity are good motives.
For much of the last decade, the bubble in equity markets was sustained by what was known on Wall Street as the 'Greenspan put'. Put simply, the rule stated that it was perfectly safe to invest in equities, since if they fell, former Fed chairman Alan Greenspan would always wade into the markets with a series of interest-rate cuts to bail them out. Now we have something that looks like a QE put – when markets collapse, central bankers will print more and more money until they get them moving again.
The freedom of speech and the freedom of the press have not been granted to the people in order that they may say things which please, and which are based upon accepted thought, but the right to say the things which displease, the right to say the things which convey the new and yet unexpected thoughts, the right to say things, even though they do a wrong.
Samuel Gompers, Seventy Years of Life and Labor, 1925
