Putting the price aside first, having a good quality means that you can use incremental capital at a high rate of return over a long period of time. And having a poor quality company means that the situation must be the opposite, that is, the company always uses more and more capital at a very low rate of return.
把价格先放在一边，拥有品质好的企业就意味着：在很长一段时间内，可以以很高的回报率大量使用增量资本。而拥有品质很差的企业则意味着：情况必定与之相反，也就是说，企业始终以很低的回报率使用越来越多的资本。
