When a feckless twit like Lee Hsien Loong is at the helm, there are only two kinds of people which flock to him: fools (Heng) and flatterers (Chan). All yes-men and political eunuchs.
Even LKY, despite his flaws, could assemble a team which would provide good advice and a little pushback if the situation required it e.g. Goh Keng Swee.
Be careful who you give your strong mandate to.
