That guy is so annoying his subpar analysis has become such a trope. America used to build things too. Lawyers have been part of the founding and fabric of both societies. Trying to reduce China v America to engineers vs lawyers is so reductive it's just mind blowing this keeps getting repeated.
I've only listened to one interview with Dan Wang, but I understood him to be particularly talking about the politicians, not the country as a whole.
I can't speak for China, I've only visited a few times, but in the US it's true that an overwhelming number of successful politicians were previously lawyers. Which is not a good thing IMO.
If we wanted to strictly enforce speed limits, we would put governors on engines. However, doing that would cause a lot of harm to normal people. That's why we don't do it.
Stop and think about what it means to be human. We use judgement and decide when we must break the laws. And that is OK and indeed... expected.
The real reason is that speed limits are generally lower than the safe speed of traffic, and enforcement begins at about 10mph over the stated limits.
People know they can get away with it.
If limits were raised 15% and strictly enforced, it would probably be better for society. Getting a ticket for a valid emergency would be easy to have reversed.
