Which it will never be.
With government, at best, you'll have maybe 20% of the money collected being used in a proper, efficient manner.
Government is powerful, and that's about it.
It is not wise, it's not intelligent, it's not thoughtful, it's not a whole lot of other things that we wish it would be. It perpetuates itself, it promotes those who promote themselves, not those who merit those promotions with their ideas or ability. One only has to look at the last 20 years or so of leadership in the US to see that.
Power, especially the power that derives from the consent of the governed, attracts psychotics and sociopaths and other people with serious mental issues.
We have to assume that money collected in the form of taxes will not be spent wisely, because we have had no indication recently that the opposite is true.
Taxes, especially involuntary taxes, are never good for anyone other than those who cannot provide for themselves - just like having someone come into your house and take your TV isn't good for anyone but the person doing the stealing.
