WOTC - Minimum wage law

I asked this question in the Wisdom of the Crowd:
Should Singapore introduce a minimum wage law?

Here are the responses:
77 % - It ensures that all workers each wage sufficient to meet the cost of living
11 % - It will reduce inequality.
9 % - It will increase the cost of living.
4 % - It pays too much for bad workers
