There will be another recession. Agree. Also agree that the next recession could be much worse but I'm not as certain about this as you seem to be. I don't think there will be a recession or even a market correction in next six months. My guess is after the 2018 election.
For one, the economy is well into the time when boomers reach retirement age. They aren't retiring at the same age as earlier generations. While this stifles wages and development of younger workers, it is a plus for the economy in that elderly continue to be productive and producing whatever it is they produce. That the older workers can't retire is a different issue. Baby boomers doomed themselves to this situation when they allowed unions and pensions to become things of the past (Fk Reagan). Also they were idiots on how they used debt but that is also a different issue.
For another, the gig economy is growing and I'm not all that certain it is a bad thing for people to be free to innovate with how and when they work. Maybe the gig economy isn't as good for the working class as a union-based workforce but it has potential to be better for businesses and workers than the non-union worker-employer relationship, including the dismal conditions of the contract workforce. From what I've read, Uber sucks, so maybe not all that good after all. That said, the gig workforce is here to stay. To me, the gig economy is an unknown variable and only time will tell how the new worker-employer relationship works out.
So, yeah, this post-great recession economy is not stable and will collapse. Maybe not the grand mal of all depressions that some people say but it's going to hit everybody, young and old harder than the one that started in 2008.
