Thank you all for your replies. I think one important distinction to understand is that distributism is not socialism/communism. The goal of socialism/communism is the eradication of private property and its concentration in the hands of big government, while capitalism (which is not a synonym for free market) is the concentration of property and the means of production in the hands of big businesses. Distributism is pro-property, aiming for having as manner owners, both of property in general and especially the means of production, in as large a segment of the population as possible. Rather than three-fourths of the population working under the other fourth, the latter owning all the means of production, in distributism most people would own what they produce and the means by which they produce it. They would then receive salary directly based on their production, and the economy would focus on producing/consuming instead of buying/selling, as in capitalism. This is essentially the ultimate free market, ‘free’ in the Catholic, not anarchical sense.
Now, back to my original topic. I’m not very familiar with the Tory party (I’m an American), so I can’t say how it might fit with distributism. However, I don’t think Centrism is really the best route, especially because in modern republican states, parties are not only economic and political but also moralistic, and so voting often has as much to do with morality as with practicality. But, I definitely think cooperatives between small businesses, as well as in specific industries in a wider area, could help satisfy subsidiarity and avoid monopoly and the price gouging methods of big corporations.
