Doesn't seem like the FED has much control this time around considering the 10Y T bill (and 5Y) continues to march higher even with the FED fund rate dropping.

You can't control everyone everywhere, especially if you have mid size team and hundreds or thousands of customers who submit tickets on daily basis.

He bought a town in Texas (yes, the whole town), but started with land and may have dealth with this issue.
