Imagine what you'd get if you allowed government to collect and share accurate data.
The department invested heavily in providing timely data to farmers, so that they could make more rational planting decisions. It ran the country’s weather-forecasting system. And its statistics service adopted crop-reporting systems from Europe that allowed it to provide independent crop forecasts—forecasts that, among other things, dramatically reduced speculation bubbles. (In 1927, Republicans, prompted by aggrieved New York speculators, managed to prohibit the U.S.D.A. from releasing the forecasts; the program was reinstituted three years later, following an outcry from farmers.)
Too bad you can't trust government to help solve problems because it just might lead to some good practices.
