What is the end game of the CECA debate?

Serious post. What do people actually want? This question is rarely asked.

Is it repatriation? Prohibition? If it is these two, what happens to CMIO ratios? How will the ratios be upheld to balance out the huge inflow of ethnic Chinese immigrants?

Because the way I see it, enforcing this country-specific immigration ban that this subreddit wants would result in Singapore becoming close to 90% Chinese, assuming current inflows of ethnic Chinese migrants are sustained.

Then what comes afterwards? We accept our newfound status as a Chinese-r country and force minorities to adapt to second class citizenship in the new Singapore?
