By introducing a civil service aspect to voting, you immediately disenfranchise all those who are ineligable for such service.
They could be too poorly educated, don’t they have a right to demand better education ?
They might be bedridden, don’t they have a right to demand better healthcare provision ?
They could be those who simply failed a urine sample drug test, they may actually want to vote for someone wanting to legalise cannabis.
There are only a certain number of public service posts available, its not possible to have even the majority of the population working for the state for the qualifiying period of two years.
What would qualify as public service and what would not ? Are we talking of those who work for the state, or the federal government, or just those in the military, or will we include those who work in charity shops, what about those caring for elderly relatives ? I can think of plenty of deserving cases who for reasons completely outside their control are unable to take up public service - which reminds me, do the physically disabled get a vote then ?
Plenty of public servants are arseholes of the highest order, and from what I’ve seen, quite a few struggle to read an write.
For some public servants, especially in the lower orders such as cleaners, etc, it may be the only job they could get.
So there is no specific reason why someone who has been in public service is any better qualified to understand the issues and vote better than anyone else.
As an idea it is utterly unworkable, as a principle it utterly sucks.
If you want better voters, then the answer is to address the problem, educate them, give them a stake in society, something to care about, campaigning and activism. Why does it seem to be that education funding is the one thing that seems to get attacked, education standards are dumbed down so that we can all achieve a mediocre level of understanding, which we then call ‘uniform success’ or ‘no child left behind’ - which actually means no child forges ahead, no child exceeds, no intellectual tall flower among that crop of plain old grass.
