Government are representatives chosen by the people to govern the
country. Thus there is a need for election every few years and
people get to choose their representatives the want to represent
them.
Government "by the people, for the people" was probably started
by some immature idealist, and it's does sounds pretty catchy and
right at the same time. But unfortunately, that is only smart
enough to fool common people who couldn't bother to use their
brains to understand the true meaning of a government.
Government is not a bunch of "People's Nannies" and neither it
is servants of the people. It's really a bunch of selected people
chosen to represent and govern the country that's all.
You can always choose to vote for your own representatives. But
if the majority voted against your choice of representatives, then
do you have what it takes to convince the majority?
Govern is to rule, maintain, control, grow. Are you really naive
to believe the people put the government there to govern the people
who chose them?
You can think again, government is to govern a country or
people? If the country is happy and doing well in the world, maybe
the people are just plain retarded not to realise it. 
You must be pretty powerful to call Abraham Lincoln immature
when he said that
Govern is to rule, maintain, control, grow. True. But that's
still for the people, isn't it?
To govern a country, you help it grow, etc etc. That's still for
the people right?
Representing the people.... that's still for the people right?
The term "for the people" just encompasses too many things
:(
