When banks implement blockchains, will their version allow tracking of all the individuals involved in the whole chain?
Of course it will. They want to use a blockchain for maintaining an efficient high-speed ledger of all bank-to-bank transactions. When you do a funds transfer from, for your account to an account at another bank, they'll write an entry to the block chain and both parties will be able to validate the time at which the transaction occurred. Having an unforgeable ledger is the entire point of the system that they're proposing.
There's no vast left- or right-wing media conspiracy. There's a small number of owners of the mainstream press, and they will not print anything that directly contradicts the interests of these owners. This has no allegiance to any political party or ideology other than a desire for certain individuals to increase their personal power.
Various governments have allowed mergers and acquisitions among news companies until there's very little independent press. Most countries don't want to regulate press freedom too heavily (for good reason - there's a very fine line between regulating truth in journalism and forcing propaganda and it's incredibly easy for the former to slip into the latter), so we're left with the majority of the population being informed by untrustworthy sources.

Sounds like missile homing! That should be fun.
