> We know exactly what to do; let's get going.

I'm not sure you're engaging with the word "illegal". If someone did what they've been successfully doing for generations they will be fined, arrested, have their business dissolved or otherwise made to change their ways.

> In what way is it better to live in China?

I usually refer to https://ourworldindata.org/grapher/per-capita-energy-use - their per-capita energy use is ahead of the UK and the trends on the chart favour China. I'd expect life in China to be better than in the UK in the next few decades if those trends don't do something radical (and when it comes to democracies vs. authoritarians, anything is possible).

But more importantly, the trends massively favour China. What they are doing is building a place that would be nice to live. The Anglosphere is letting a nice place to live slowly decay because we aren't willling to maintain it. For all the bleating about how we have to do more for poor people, we've made no attempt to double per capita energy use in the way China has; there have been explicit policies trying to reduce it. Largely, I point out, because the obvious way to get more energy from where we are is continuous development of Nuclear power and it has been banned in practice.

> Why are so many in China moving to the Anglosphere these days?

I dunno, are they? I'm sure they'd like to, the US is still a long way ahead of where China is.
