Why the cost increase?

As I said earlier fact free.

The only reason for the 33.8% 3rd quarter 2020 increase in GDP was because it followed the -31.2% (decline) in the 2nd quarter GDP in 2020. Ya can’t just tell part of the story

Agreed, social arts derived economic comparisons are pure stupidity. 

However, if you had read the thread you’d have seen my post was in response to a post crowing about Liden’s 6.4% quarterly growth; which the poster compared to president Trump’s yearly GDP numbers. I was simply putting it into perspective. 
I doubt we’ll see a yearly GDP growth of > 2% under Liden, nor another 6.4% quarterly growth number. 

Such a tool.

Beaten to the punch, again!
Here, from the very same site good ol’ pauly cites is the evidence of his cherry picking:

Are you under the influence perhaps?

You compare Liden’s quarterly numbers against Trump’s yearly number, and I am cherry picking? Are you really too uninformed to understand that comparing quarterly numbers to yearly numbers is apples to oranges? (That’s a rhetorical question)

Until the Fed releases the GDP growth for 2021, which will probably be sometime Feb 2022, you have nothing to say sunshine. Let’s see where he ends up before you spout off …

President Trump’s 34% GDP growth in the 3rd quarter of 2020 is the most rapid growth in US history. Period. That’s just how the ball rolled, that’s how the numbers turned out. That’s what’s in the books. That’s part of US history now. Deal with it sunshine. Trump was well on track to break 3.5% GDP growth for 2020 if not for COVID. But COVID did hit, and he didn’t achieve 3.5%. That’s life.

Best leave economics to those who understand. Stick to what you know best, you know; emptying bins, busting tables and spending on that EBT card of yours.

Such a tool.

Again, the childish behavior of resorting to vitriol when not being able to argue against somebody more capable.

Tut tut. You need to grow up.
