Fascism is a political philosophy that precludes top-down corruption, but it can only work well in homogeneous divisions. The bottom-up approach has the same problem: unless you have homogeneity, you have harm to a significant part of the population. So the bottom-up approach works if you have tiny (neighborhood sized) political divisions, whereas fascism codifies that which would have been voted from the bottom up into law and order. These are very close to the same thing.
