You are an idiot.
Having UBI, as your parent proclaimed, China might try soon, has nothing to do with a planned economy.
How could it? How should it?
I'm a programmer. The ice in my fridge is colder than yours.
You see!? Two statements that having nothing to do with each other. No conclusion possible from one to the other. Both even might be false, or true, who knows.
Regarding the paretn. China does not need UBI, yet. The evonomic growths is much to fast. They likely will invest into education, as they did the last 70 years, instead.
The first UBI nation likely is a Scandinavian one, Netherlands or Germany. Possibly Japan.
