The TTIP could force privatization of national health systems, in the UK and (I presume) in the rest of Europe.

It could also stop the US from setting up a proper national health service, which it badly needs.

The UK has treaties with many very poor countries, limiting what taxes they can charge to UK companies.

Sanders plans to solve two US problems at once: curbing speculation in the big casino and funding US infrastructure.

Incidentally, rebuilding the infrastructure will create lots of jobs.

A disabled British woman, and her husband that cares for her, may become homeless because of the "bedroom tax".

The Tories keep imposing cuts on the poor and sick, which they know must push increasing numbers of people into penury. Precisely whom or why, they don't care. The cuts must be applied rigidly, even dishonestly, or they would not achieve the goal.
