Children asked me why CNC machine tools were expensive in the early 1980s, and what was the appropriate answer?

At that time, technology was monopolized by western countries, and R&D institutions had not recovered the patent cost. So, it's more expensive. As long as the national manufacturing industry is strong, foreign products will naturally reduce prices. China and the western developed countries have overtaken for a hundred years, and they must pay a great price. You see, mobile phones, computers and other electronic products are getting cheaper and cheaper now. Because it is made in China.
