Why the cost increase?

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. 

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. 

There is about one third of one ounce of gold above ground for every man, woman and child on earth. The gold standard only works in a closed ecosystem with a limited populace. 

Your reasoning is incorrect. The amount of gold is irrelevant. The value per ounce of gold would increase to compensate for population growth. (Increase in demand)
That is how crypto currencies work. The amount of currency remains consistent, the value increases to as the demand increases. 

At least Nixon listened to someone intelligent during that dark time period in history.

That is correct. Unfortunately the intelligent people Nixon listened to are evil and self serving people and the world is much darker now.
Since we moved off the gold standard, the Fed is free to print as many USD as they please with no backing whatsoever. And they do. Each time they do, your salary, your savings and your pension loses value. 
Since we’ve gone off the gold standard, our money has been losing value faster than our incomes have risen. 
The Fed is a private organization that is never audited, and the public has no insight as to who owns the Fed.
