although there are possibilities that some of the leaders may not be corrupt but there are more corrupt people out there
I also think that there should be at least one leader that is not corrupt but even if there is one, it still hard to make positive change with the rest of the government being corrupt and I also think that there are leaders that started with pure intentions but once they get into the position of power and wealth is becomes corrupt.
Yeah true, there are leaders that may have started with pure intentions. But with the way the system is, they may have chosen to go with the flow. Like if you are in Roman, behave like romans.
It is hard to enact positive change when the organization and the whole system are against you.
