"在某种程度上，谁在任职很重要，但更重要的是他们受到公众多大的压力。"

Simplified Meaning:

The quote means that while the leaders we choose are important, the real difference comes from how much people push them to do the right thing. When a lot of people speak up and demand change, leaders tend to listen more and act on those demands. This is because they want to keep their jobs and stay popular. For example, in history, civil rights movements showed that when large groups of people protested and asked for fair treatment, it led to important changes like the ending of segregation laws. This happened not just because of the leaders in power, but because a lot of people stood together and made their voices heard. So, if you want something to change, it's not enough to just vote for someone and hope they'll fix everything. You also need to join others in speaking out and letting the leaders know what you want. The more pressure they feel from the public, the more likely they are to take action.
