China has already learn the biggest lesson from the Singaporean system. And that is pragmatism and do not dwell on blind faith in political ideology. China has wasted nearly a century on political idealism. With million of lives lied in ruined or destroyed. Stability and solidarity is an essential and necessary condition to bring wealth and progress.
The Chinese politicians concentrate their energy on getting thing done and improving the life of their citizenry. Not on pie in the sky ideology and infighting.
In all metrics, China is doing fine. Don't believe in all those chicken little that is crying the sky is falling down. They are just exaggerating in the hope to weaken China in-order for them to gain power.
In my opinion, to give up the learned and proven lesson to pursue some unproven promises is stupidity beyond believe.
China is not broken, please don't try to fix it.
