In Gulliver's Travels, what in the king of Brobdingnag's criticism makes you think that Swift was satirizing his own society?

In chapter 6 of Gulliver's Travels, the king of Brobdingnag makes several questions about England's government. After listening to all that Gulliver had to say, and taking notes, the critics the way things are in Gulliver country, by saying that lazy and ignorance are the best ingredients to a governor and that the laws are better explained and put into practice for those who have interests in fraud them.

Swift uses the king's criticism to satirize his own society, in which people don't need to prove their values or to be honest to rise in life, and that the ones who fight for power are usually those who have interest in taking advantages of power.
