Can Singapore afford to remove GST?

I asked this question in The Wisdom of the Crowd - Can Singapore afford to remove GST?

Here are the replies:
74% of the people who voted support this move for two reasons. The remaining 26% like to retain GST for 3 reasons.

By the way, I debunked the three reason in my speech in Hong Lim Park on 3 March 2018.
