It's an interesting video without much meat in it. They talk about the "bubble," but don't explain exactly what that is. That's what I call "fear mongering." It works with most people, because most people do not understand economics.
Today's world is much different from the past. Nobody can predict the future of the world's economy; NOBODY. How can they predict a bubble when nobody can predict the economy of the future? It can't be done. I't fear mongering.
Look at it another way. We all understand that wealth has been accumulating at the top. There are enough research to prove this point. If, as they say, 20% of the people owns 80% of the wealth, where is the bubble?
The wealthy folks aren't going to all of a sudden start spending their money on all manners of consumables. They don't need to - or care to.
That sort of takes care of inflation, because the 80% of people are going to spend their incomes to "live." That means mortgages, cars, and other consumables are being "demanded and bought" by the majority of consumers with limited income/assets. With this lower demand for goods and services, companies can't afford to keep raising prices.
The so-called debt that the US now has is small compared to what happened during WWII. Debt as a ratio to GDP was 120%. The US debt is now dropping in relation to GDP.
Current debt is now equal to GDP, but the fact that the ratio is dropping bodes well for our country. After all, the greatest portion of the debt was created by the GW Bush administration over four years ago, and carried through to Obama's administration with the carry-over of two unfunded wars and drug benefit.
I say, we're in pretty good shape when observed in macro-economic terms.
The two wars have been winding down, and our economy continues to grow - although slowly by past standards, but growth in a world in recession.
I say the cup is half full, and getting fuller.
