He is a very boring PM, and lacking ambition of his father. Singapore under him is in "maintenance only mode."
We could do with boring in the UK right now.
He certainly inherited the size of the mouth of his father, and tried to imitate his tirades heavily 12 years ago when I lived there, but so far nothing really came out of it.
Sing in last 12 years: losing vestiges of its industry, and getting more, and more reliant on mainland money.
I would say 1 thing: Singapore is probably the only country in the world which actively tries to reduce population of millionaires, and rich 6 digit salary making expats on the populist notion that this tiny population which pays for itself n-fold in taxes is "stealing Singaporean jobs."
