I love my country and for the most part trust the Government... but on the same token - you'd have to be blind not to see how inefficient they are compared to private organizations (IE: Post Office compared to FedEx. Private Hospitals compared to the VA.)
You'd also have to be blind to not see blatant growth and abuses of privileges. The ACA growing government meddling in healthcare. Snowden - and similar - releases showing abuses. Daily revelations about different groups abusing their privileges.
"Arguments like this" continue to be made because examples are PLENTIFUL of how inefficient, self serving and abusive large organizations get. The same can be said of Unions - which are great in some aspects... horrible in others.
