I have to come right to the point because I am worried that even a person with a Ph.D. still misunderstood my point. Perhaps I did not speak clearly enough, but when I reread what I had written from my peech, I thought that it was clearly stated that 50 per cent sufficiency or even only 25 per cent sufficiency would be enough. I meant that the application of the sufficiency economy does not necessarily mean full sufficiency, and I may add that full sufficiency is impossible. If a family or even a village wants to employ full sufficiency economy, it would be like returning to the stone age.
