You can eliminate middlemen if you can show cost reductions for a player larger than the middleman. The big players are providers, payors and technology (pharma/device) companies. Plenty of middlemen in between those that can be made irrelevant.
And if we get more productive disposable income will go up and that will feed into land prices.
All the rentier need do is wait.
edit: would love to hear the counter to this from whomever downvoted me - it's a fact that with our system productivity improvements flow into land prices therefore speculating on land sees you capture these gains.
That is actually one of the secrets to a lower stress longer lasting life IMO.
"Data releases have become much less transparent and truthful at both a macro and a micro level. At a macro level the key issue is the ever increasing importance of China and India. China is the world’s second largest economy, but already much larger than the US in a broad swathe of sectors. India will be the world’s third largest economy within a decade. Unfortunately their rise is increasing the global cost of capital because an ever growing share of the most important data they produce is simply not credible. Currently stated Chinese real GDP growth is 7.1% and India’s is 7.4%. Both are substantially over stated. This obfuscation and distortion of data, whether deliberate or inadvertent, makes it increasingly difficult to forecast macro and hence micro as well, for an ever growing share of our investment universe."
