Think of any huge, major undertaking - whether public or private; there will always some that succumb to temptation.  Can you think of any exceptions?

But look at the current administration; appointments of incompetent cronies, corrupt contracting, propaganda camouflaged as news paid by tax dollars - it appears to be entirely systematic.  Insane tax cuts benefiting the richest.  An immense, thorough, relentless undertaking of further enriching those already excessively privileged.
OK, enough.
