Debt is the accumulation of deficits and deficits are actually a projected number that isn’t always precise. Just making people aware of what the debt represents should be sufficient to cause the right to not want to mention it again.
I’m just not sure of the mechanics of making such a complex aggregate fall into a number that can be pinned down beyond an informed guess. It would have to include all of the national debt plus any private investments in banking and finance, including everyone’s 401k. The Fed attempts to do this by its computation of velocity of capital. The higher the number, the smaller the percentage of currency is stagnated. Even this is skewed heavily by such things as automated trading though.
