in general that's true.
some fine points...government (any government) is not monolithic.
the bigger the government (any organization really) the more subunits it is composed of.
each of whom (which?) are interested in their OWN perceived best interests.
They'll do anything they can to achieve that.

That means they'll fight OTHER government agencies for a bigger piece of the pie, while oppressing their citizens for a bigger pie.

Of course the pie gets smaller.

Societies progress in spite of government (any form of government) not because of it.
Socialism is a more lethal form of government than crony-capitalism.
