I'm not saying blame anything.
Facts are facts though since after WWII, we had a population explosion ie: baby boomers. The biggest market booms are the ones that follow that generation. That's going to happen all the way to the grave. When we where young kids it was toys, teens it was records, audio and events, later teens and young adults it was the muscle car wars. Then it was housing, and a boom in US jobs and production, then it was sending our kids to collage with the income earned. Then it's empty nester time having fun, travel, remolding homes and buying things we used to have and nostalgia, back to the muscle car, records, audio and events.
The last 15 years the medical industry and everything related to it is booming and next will be Funeral industry.
In fact the DMV is wondering what to do with all the elderly still getting a license. This is going to be fun, the youth driving and texting and the elderly with bad eye sight and reflexes.
