My views on the Ukraine conflict, a narrative thread:
TL;DR - Russia invaded Ukraine because the West wouldn't give them what they want, ignoring their demands, and Putin prefers invasion to the status quo. But so does the US! The US sees this as inducing a strategic error.
Russia and particularly Putin have grievances. They say them and mean them. Putin thinks the USSR made lots of mistakes, weakened Russia, and then the US took advantage of the collapsed USSR, treated Russia as an enemy rather than helping.

2yrs ago, we were already in isolation, my wife had bought a deep freezer and lots of food. We're prepper types... but by late March it was clear the death rate was much lower than it could have been.

@The_DTCC should clarify what actions they took around increasing margin for the short squeeze names many brokerages restricted yesterday.
If they raised the margin brokers have to post on GME to 100%, it raises legitimate questions. Another natural question is regulatory role.
I tried to figure out what was happening yesterday but the size of capital @RobinhoodApp raised and the actions of other brokerages indicate that DTCC may have added specific margin add-ons for GME and other highly correlated stocks.
It does confirm that solvency concerns drove the restriction. You don't raise 1bn of equity to cover your tracks if nefarious, nor if the restrictions were a tap from regulators.

Ok - here's my best explanation of why @RobinhoodApp restricted trading in the short-squeeze stocks.
Spoiler: the story isn't the Ken Griffen called Janet Yellen who instructed DTCC to raise margin on Robinhood to force them to shut down the speculative buying.
Here goes ...
Robinhood (RH) is a broker. They don't execute stock orders themselves. They sign up customers, route their orders to executing brokers, and keep track of who owns what. RH is also its own clearing broker, so they directly settle and custody their clients' securities.

Just so bad.
If we had only hairdressers immigrate, it would depress hairdresser wages.
Also, we wouldn't become hairdresser to the world.
But does allowing software engineers in reduce incomes? Of course not because it's part of having the winning products and services.
