Why do a lot of people dehumanize government employees?

I have thought about this in the past, but the recent aggressive trimmings in the US federal government workforce made me think about it again - basically most people who claim to be nationalists often talk about unity, jobs for natives, etc. However, it appears to me that many of those same people absolutely don't use the same rhetoric when they talk about their fellow countrymen who're in government service. When it comes to government employees, a lot of people are suddenly very nonchalant or even ecstatic about people losing their jobs in hundreds if not thousands, so my question basically is - what happens to the sense of solidarity in these cases?

FWIW, it seems to me that the answer can't just be financially motivated, i.e. the school of though that a smaller government workforce will translate into lower taxes which in turn will put more money back into the pocket of ordinary people. The reason I say this is: A government can slim itself down to the bare bones, but then it will need to outsource a lot of its current work to government contractors. There is no guarantee that what the government saves in payroll & pension won't be lost in third party costs.

PS: Although I mentioned the US in my opening line, this post isn't specifically about the US government, or the American people. Its about the general dehumanization of government employees around the world by their fellow countrymen.
