"copy and paste," too funny, "post some examples," usually it is "prove it, we'll understand if you can't," predictable, I'll just a quick look at the big three And even throw in the President's favorite; Thanks for proving my point
From your first "example": "But most economists took issue with that forecast, saying the pace of growth in the April-June quarter won't likely last in the months ahead. Forecasters cautioned that the April-June pace was due mainly, though not entirely, to temporary factors. Many think the annual 4.1 percent growth rate last quarter is likely the high point for any one quarter. 'We believe quarter two will represent a growth peak as the boost from tax cuts fades, global growth moderates, inflation rises, the Fed tightens monetary policy and trade protectionism looms over the economy,' said Gregory Daco. Another key factor that bolstered growth was a rush by exporters of soybeans and other products to move their shipments to other countries before retaliatory tariffs in response to Trump's tariffs on imports took effect. 'The second quarter was a strong quarter, but it was juiced up by the tax cuts and higher government spending,' said Mark Zandi, chief economist Moody's Analytics. Zandi forecast that growth for 2018 will reach 3 percent, which would be the best rate since before the Great Recession. In 2019, he expects solid 2.6 percent growth. But in 2020 — a presidential election year — Zandi is forecasting growth of just 0.9 percent, a pace so slow it will raise the threat of a recession. 'We will come pretty close to stalling out in 2020 because the growth we are seeing now is not sustainable,' Zandi said."
