Can someone explain the $2 trillion Trump double-count math error to me?

Not trying to be political, just trying to understand the issue that everyone says seems to be a basic math error. I don't believe that trickle-down works in the vast majority of cases but let's just assume it does, since that's the assumption from the budget proposal.

****

Let's just say that the people collectively earn $10,000 and the government taxes at 20%, so the government collects $2,000.

The government then cuts taxes to 15%.

The people collectively earn $10,000 and the government taxes at 15%, so the government collects $1,500.

****

But the belief is that by cutting taxes to 15%, the economy will be spurred to grow.and the people will have more money, thus...

****

The idea is that people *no longer* collectively earn $10,000. They earn $15,000 because the economy grew as a result of trickle-down tax cuts..

15% of $15,000 is $2,250, which is $250 higher than the original $2,000 that the government collects. The idea is that the government will collect more tax revenue while having a lower tax rate because the lower tax rate spurs economic growth which means people are richer and thus pay more in taxes, despite having a lower rate.

****

So the government is predicting that their tax cut from 20% to 15% will bring in an increase of $250 in government revenue. It then expects to use that extra $250 to pay for stuff.

Where is the double count?

Basically the problem is that the stated problem is that The Tax Cut of $2 Trillion(IIRC) will be recovered from GDP Growth. However, that same $2 trillion due to GDP Growth is also being claimed to reduce the Deficit/Debt of the Government. The conflict here is that the Tax Cut decreases Income, thus increasing Deficit/Debt, so if the GDP Growth recovers the Tax Cut Income loss, it only recovers the lost Income of the Tax Cut.

Sandorski got it correct. Using Fuzzy's numbers, the Trump budget says that not only did cutting taxes not lose the government revenue from $2000 to $1500 ($500 recovered). But it also drops the deficit by $500.

If the government was spending $2250 before and collecting $2000 before, then the deficit is $250. After, if everything Trump predicts is true, then cutting taxes will get $2250 government revenue. Combined with $2250 spending, the deficit is $0. But Trump claimed the deficit will drop by the same amount as the recovered revenue ($500). The deficit didn't drop by $500 though. That is the double counting.

That said, in no time in history did a tax cut grow the economy by the 50% needed for this example. Heck, there is very little evidence that any tax cut has grown any economy.

Ok, so put into numbers, say that the government takes in $10 trillion but spends $11 trillion. The deficit is thus $1 trillion.

They want a tax cut of $2 trillion, which means they'll now have $8 trillion in revenue, BUT that $2 trillion will be made back in economic growth, so now they're back to their original $10 trillion.

If they continue to spend $11 trillion, the deficit is still $1 trillion because they're still taking in $10 trillion.

So.... what they're claiming is that the deficit will now somehow, uh, be a surplus of $1 trillion instead?

+$2 trillion extra revenue (which has already been counted) + -$1 trillion deficit = +$1 trillion surplus?

Fuzzy math has been used forever. By every administration. I even use it on my kids.

It's fuzzy math that is banking on something that rarely happens to re-enforce their numbers is how i take it. I could be wrong. Im not great with all this tax stuff lol

I think they're not only 'banking' on it, they're doing that and then double counting it.

Yeah, this is worse than just fuzzy math. They're double-counting the fuzzy math.
