I suspect already worst as for the last 5-years I saw many job suitable for polytechnic and local u-grand taken up by indian and Philippine degree holder in building, electrical industry.
few years back one facade company with 3-degree Philippine site engineer not able to update the autocad drawing 6-weeks after site meeting.
one electrical company with vietnam site engineer tell the architect to mark the cable route so that he can advise VO.
all these are incompetent foreigner taking job from our Singaporean for salary between usd-1500 to usd-4500.
means Singapore polytechnic and university is same level as india and Philippine's
