Kouye please go to your nearest university and ask a random economics student if your ideas will work at any point.
When for small communities this may somehow work then for bigger (starting of town scale) it just won't work at all.
If that is your imagination of country then I for sure don't want to live in anything similar. I just care about my future and my family - thats most important.
That's actually part of my point. To acheive this, we need to break up into much smaller units, and forget about huge nations.
The only way to participate in "efficient" taxes is local, of course.
Which is why I attached a "tax-map" idea, also voted by tax-payers.
And when you pay for your local hospital, you also pay for research for cancer cure, for example. You have no choice, because cancer-cure have been attached, through voting, to local hospital funding.
I might be dreaming. But it looks pretty realistic, if you forget about what's happening now and focus on what could be happening.
