When old lee start to ask investor to open business in Sg, it may work.
Now if minimum wage laws kick in will be a sudden large increase of operation cost that stress investor to shift their operation to another country.
So the answer is no.
However our government can lower foreigner intake by limiting Work Pass holder especially like E-Pass holder to compete jobs that Singaporean want to do.
Another thing our government can do is by dividing Singapore Citizen & PRs for quota system instead of current system of combining together as 'Local full time employee' which will force organization to have at least 1 Singaporean instead of fully relies on foreigners especially PRs (and E-Pass Holders).
Apart from that, as a wealthy & high cost of living country but very limited & low amount of welfare to their citizen, government can consider giving some reasonable amount of 'allowance' while helping their unemployed/retire citizen to look for job which include healthcare benefits too.
