They actually are the ones that can influence the change but greed, I believe, won't let them.
This morning, I overheard over the radio where a senator in my country said he needs 2 come back for 2nd tenure 'cos the office is not befitting for youths
So I believe they only think of self instead of the masses.
That's why am always glad I found steemit when I did. Thanks @famunger for sharing this interesting experience
