Don't act daft, Remius. You know very well that is not what this graph shows.

What we have to look at is that, in 2014, the Harper government had a plan for dealing with public finances that would have seen surpluses small at first, then increasing, that would have wiped the national debt by 2038, based on current projections.

Then, the Trudeau government came along and introduced a new, high spending plan. That plan, when projected in the future would not reduce, but rather double the national debt in the projection horizon of 30-33 years.

The important figures to keep in mind in our shorter term horizon of one to three election cycles is that, by the end of their current mandate, the Liberals will have added 146 more billion dollars to the national debt than the Conservatives would have under their plan.

Second thing to realize is that, if a new government wanted to go back to the Conservative plan's level after next election, they would have to be able to generate an average of $55 billion $ surplus in each year to do it in a 5 year horizon or a 45 billion$ in each year to do it over a 10 years horizon.*

Another way to look at what the Liberal plan is doing is the following: Imagine that after the next election, the new government wants to make debt reduction an issue again. First, they would have to eliminate the operation deficit in the budget (i.e. "balance" the budget). Then debt reduction can slowly start. To imagine, mentally move the Conservative plan line down to the Liberal debt level for say 2023 (balanced budget 1) and, because we are staring from a greater debt and the greater, the harder to get out of it, flatten the Conservative curve somehow: then look how far to the right the "zero" debt intersection occurs in terms of years. It's probably somewhere around eight to ten years later.

There will be pain and suffering all over again and bigger than what it has been under Harper (because most of the pain had already been inflicted by the Harper government to get to this debt free status).

* The calculation is actually a matter of differential equations resolution as we are dealing with two curves and the difference in the surface between the two curves. However, an easy and quite valid evaluation is to do the following, which is what I did: (1) take a given period; (2) calculate the difference between the number generated by each plan at the beginning and then at the end of the period; (3) average the two numbers; and (4) divide the resulting average by the number of years in the period. This gives you the "average" surplus that must be generated to reduce the debt to get from one plan to the other (smaller debt) one.

In my case, I took the following "differential" figures: in 2021, 150 billion more $; in 2026, 400 billion more $; and in 2031, 750 billion $ more.

So: 5 years horizon: $(150b + 400b)/2 = $275b, over 5 years (divide by 5): $55b.

10 years horizon: $(150b + 750b)/2 = $450b, over 10 years (divide by 10): $45b
