There is strong evidence that attempts to fix the depression actually made it worse and prolonged it. One take of many: https://www.econlib.org/policy-failure-during-the-great-depr...

Article claims USA/Europe no longer have crop reduction policies in place because "they know that producing more and exporting it brings greater benefits than reducing the amount produced." Japan's approach does indeed seem more controlling. Whether that's good or bad, I don't know.

Edit: Article also says "western" countries subsidize farmers to protect them from price drops of oversupply.
