Once again: Tor timing attacks and a Tor confession

Email I sent to cypherpunks, so far the flamewar is low:
https://cpunks.org/pipermail/cypherpunks/2016-February/012436.html


Searching the web for "tor timing attacks" (without quotes)
returns too many hits.

Short summary and PoC is at [1].

At [2] Tor (and/or DoD) confess:

>The Tor design doesn't try to protect against 
>an attacker who can see or measure both traffic 
>going into the Tor network and also traffic coming out of the Tor network.

NSA and the like  definitely can "see" traffic almost everywhere,
so Tor doesn't protect against the NSA, right? (some people learnt
this the hard way).

IMHO the first fucking thing Tor must do is to make the user click
at least three times on the above disclaimer.

Trying to make the rant on topic:

Is it theoretically possible at all to make low latency anonymity
of sufficiently decent quality?

From counterpunch.org: The US Economy Has Not Recovered and Will Not Recover

From counterpunch.org: The US Economy Has Not Recovered and Will Not Recover by Paul Craig Roberts.
Some quotes:
The US economy died when middle class jobs were offshored and when the financial system was deregulated.
The debt expansion, tied heavily to housing mortgages, came to a halt when the fraud perpetrated by a deregulated financial system crashed the real estate and stock markets. The bailout of the guilty imposed further costs on the very people that the guilty had victimized.
According to a poll last autumn, 53 percent of Americans say that they feel like a stranger in their own country.
The US government will not be happy until no one lives long enough to collect Social Security.
Paul Craig Roberts is a former Assistant Secretary of the US Treasury and Associate Editor of the Wall Street Journal.
