Meanwhile, the banking and financial systems, perhaps in combination with IT, were concentrating wealth and power into the hands of fewer and fewer people worldwide. The funny thing was that, because of taxation, this wealthy elite actually felt they were supporting the rest of the population, instead of it being the other way around. The wealthy elite were now so wealthy compared with the rest that they paid a significant percentage of total taxation, and therefore believed they supported, rather than exploited, the masses. They seemed to have overlooked the fact that the cause of this was the masses not being paid enough due to their exploitation. Eventually, there must be a breaking point. Either the elite would break away from the rest of the population, deliberately using social spending and welfare as a means of suppressing them, or there would be revolution. That, he reminded himself, was why he was not a Social Democrat. Welfare abuse was their raison d’être. He was no longer an activist either. He had been sleeping. In fact, Richard was a card-carrying member of the Conservative party. His reasoning was that since capitalism would destroy itself through its internal contradictions, he should help it along as much as possible. It was like being an actual socialist without the hypocrisy, he reasoned. Or, actually, it was like being a capitalist – with both hypocrisy and irony.

“Stanmore!” a woman’s voice joyously exclaimed, waking Richard from his daydream.

“This train terminates at Stanmore,” the invisible woman continued.

The breathless glee with which she said the word “Stanmore” led Richard to assume it was one of her favourite places and she was very much looking forward to going back there. The Jubilee Line had an invisible woman to tell you what stations you were at, or were approaching. Soon the invisible woman breathlessly cried out “Baker Street”.

He was there. Baker Street. Almost home and safe to take a look at what he had.

“MIND… THE GHYEP!” a stern male voice boomed out from the walls of the station repeatedly as Richard pushed his way out of the carriage onto the bustling platform. The robot man warning everyone to “mind the gap” had obviously been educated in Eton or some such place. The calm, robotic repetition of this advice conflicted with the chaotic flurry of the crowds of people who gave no indication they were minding any gaps whatsoever.

During every tube journey, commuters were accompanied by invisible people offering all sorts of advice and warnings. The Jubilee Line woman was particularly posh and enthusiastic. Other lines had imaginary people of different temperaments or social backgrounds (the woman on the Docklands Light Railway serving Canary Wharf was surprisingly common compared with her customers).

Advertising vied for your attention too. There was a bombardment of excitement, beauty, witty advice, things to do, places to go. Your brain had to process visual information where what was real mingled with images from TV screens and posters, and auditory information where real people were shouted down by electronic people who had more important things to say.

In the shiny, synthetic, Brave New World of the near future, real and imaginary lives would become difficult to separate. People already existed as avatars; there was already a Sim World where people were becoming real millionaires for activities they undertook in an imaginary, computerised existence. Bitcoin too was accepted as a genuine currency and were increasing in value (though the Chinese had recently put a slight dent in that value). There was the Twitter-sphere. There was the whole Facebooking world of bullshit friendship. Richard himself had more than a hundred Facebook friends, though the only people he knew well enough to drink with were a handful of work colleagues.
