I was just trying to point a statistical truth. Blue collar whites are declining in population share, rural culture is declining, advances in technology will make the working class virtually non-existant in America by the end of the century. I guarantee it. Some can't fathom this, but the West and perhaps the world shortly after it is ascending beyond blue collar.
Who do you think is going to build future buildings, infrastructure, etc.? Robots? Capital can only get you so far with tangible production of most goods, especially with regards to infrastructure. It is difficult to make do without labor when it comes to construction of most infrastructure. For example, you cannot outsource carpentry, plumbing, electrical work, etc. Yes, 3D printing will transform traditional manufacturing, but mostly overseas. That technology is going to crush China, not us. We'll still need technicians to fix those machines, of course, which is a blue collar job when you think about it. Arguably the most blue collar job of them all is that of the soldier, and we'll always have soldiers even if robots become a reality someday in the distant future.
If anything, I see many traditional blue collar occupations gaining higher and higher wages moving forward. The primary reason: Much of today's spoiled youth is afraid to get their hands dirty, let alone bloody. Current generations of young adults and children today want lots of consumption, but many of them do not want to produce anything in exchange for their consumption preferences (there are exceptions, of course). After the Baby Boomers retire/die off, many blue collar occupations will be in robust demand with relatively low supply. Heck, we already have a shortage of welders despite the dismal economy.
