The left in general lives far too much in the past. Society screams for radical solutions, but the left is seen as the defenders of the status quo because it lacks an alternative. The vicious demagogues of the so-called populist and extreme right parties and movements such as the Tea Party in the US are filling the gap.
As for the other sectors in society: revolution is ?le mot du jour? (Fr., ?the word of the day?): they speak about the technical revolution, the digital revolution, the bio-technical revolution, the scientific revolution, or talk about the need for a revolution in education, in business models, etc. The matter of fact is, that the only people who don?t speak about revolution, is the revolutionary left. Lots of examples ca be given. Workers understand that you won?t solve the budget crisis, the debt crisis, the migration crisis, mass unemployment, etc. with a tax on wealth or the establishment of a public bank. They know that radical measures are needed.
