What else is there to say about Tonga?
It is a country with a rich and unique culture and Pohiva getting the Premiership after 35 years of struggle with great personal sacrifices is an inspiring tale.
I interpreted your comment as an expression of your pro-monarchy/aristocracy schtick, which I find a bit tiresome (when you take it too far) and in this case the establishment of full democracy will actually safeguard the monarchy (the level of corruption/abuse in the present system would eventually have undermined the position of the royal family). Next step will be for centre-right leaning independents to form a conservative party to counterweigh DPFI. The whole process in Tonga since 2010 has overall been very positive and it looks like the country is about to establish a national compromise that will allow them to move forward with economic and societal development.
