<p>It may be due to my poor English writing. My point is not who is more credible. It is assumed both statements are true. Then, the first one merely tells you who “thinks” what. Anyone is entitled to your own opinion, not matter you are a CEO or a high schooler. However, your opinion hardly represents a view held by all people in the region. The latter tells you who “did” what. Here, the “who” is an engineer working for a reputable tech company. Then, we are sure his income is representative of all people working in the same capacity. And those people happen to fall into the category of lower to middle class in China. The fact that this engineer has annual oversea vacations and can easily afford a ticket to America does tells you something.</p>
