Quote of the day: socialism has not failed

Hindi ko pa talaga nabasa ang buong article (oo, ang bagal ko magbasa) ni Pao-Yu Ching na Rethinking Socialism: What is Socialist Transition, pero gusto ko lang i-quote yung dulong paragraph:

During the past century, thousands of millions had taken up the task to advance their societies toward socialism. Unfortunately, the first round of attempts to build socialism failed. We need to learn from their valuable experiences, because thousands of millions will take up the task again in the future. Socialism has not failed, because we have not yet entered its threshold.
