Calling that "my assertion" to be taken "at face value" would be like saying "taking your assertion that plate tectonics are real". It's the dominant view of anyone who has taken a basic macro course or even thought about macro, not "my assertion" for you to dismiss as such!Taking at face value your assertion that mild inflation is desirable
I've been hearing about "the challenges of Japan's demography" for two decades, and economists have been chirping about the country's supposed stagnation and endless depression for years before that. So when is the reckoning finally going to arrive? Where are the old people dying in the streets, where's the debt implosion
Hint: Having the number 1 debt to GDP ratio in the world! isn't a positive in economics, especially when you're not the worlds reserve currency.
Again, one of the great things separating modern society from caveman society is that we don't have to wait until old people are dying in streets to realize that something is awry. Nor does your observation of 3 workers in a country not your own during a short visit make for a rigorous result to base any conclusions on. If those are your alternately absurd levels of making a determination on macro economics...., where are the falling living standards and spiraling economic collapse from falling demand or lack of workers or whatever else?
On the labor front, I was in Japan just last year and saw the same old over-employment as always. I recall the comical scene of three prime-working-age crossing guards posted at a small, lightly-trafficked intersection where some road work was underway - or would've been underway, except it was nine in the evening. This is the great world-ending labor shortage? It's all just ideologically driven nonsense.
Listen, I'm an electrical engineer by undergrad training. Assuming you are not, would you jump into the middle of a conversation about tunneling electrons and tell me that "my assertion" that such things exist is absurd (it's a counter intuitive concept) and proceed to tell me that since you've never seen a tunneling electron it must not be a thing? Hopefully you have the good sense not to, at least most moderately intelligent folks would realize they would be talking out their ass about something they don't have any background in at all. Why in the world would you think it's any different with the field of economics? That somehow your uniformed opinion is anything but babbling given your complete and utter lack of experience and understanding of the field? As Twain aphoristically said "Better to remain silent and be thought a fool than to speak and to remove all doubt."
