Now, about Postal workers ~ they are paid exclusively out of revenues raised by the USPS for carriage of the mails.
And then, there are your firemen and cops. Although they should collect fees for services provided directly to victims, we generally view them more as an "insurance" than anything else.
Think your thoughts through a bit more then get back to us with something besides libertarian talking points.
Your points are well taken. I am a long ways from being a libertarian but there are some government workers who, while their jobs include valuable services, nevertheless will always vote for more taxes to sustain themselves. I exempted soldiers primarily on the idea that no tax-paid sinecure alone would be enough to encourage someone to remain in the military with the risks it entails. On the other hand, cops and firemen do valuable work but mostly it’s a few minutes of sheer terror punctuating hours of drudge and boredom. But I should not paint with such a broad brush, as you noted.
The problem is when a paycheck depends on tax income, and doesn’t involve too much risk, the people in that career are seldom, if ever, going to vote for lower taxes.
