The love of power is common to most politicians. Giving them unbridled opportunity to exercise it is madness.
Parliaments are meant to act as a robust check on the excesses of power.
That’s necessary because politicians always think, the reasons their policies aren’t working, is because there wasn’t enough money allocated or they had too many people interfering in the decision making process.
I am yet to meet a political leader, one who is actually leading a government, who actively looks for that government to do less rather than more.
