In some ways quite the opposite. A ticket from London to Manchester at 2:30pm on a Wednesday is not worth as much as one at 6pm on a Friday. Yield management is a bit like auctioning in that it allows the price charged to be much closer to what the seat is worth - any commodity is worth the maximum someone will pay for it.
If it was always £75 single, £150 return (which is about what I reckon it would be if you did only have one fare, based on how Deutsche Bahn's pricing structure used to work), some might consider it fairer, but equally some people would be priced off entirely while some peak trains would be very heavily overcrowded. And no, they can't put any more coaches on - 11 coaches are the most that will fit on most[1] of the platforms at Euston without starting to block points and mean they can't use all of them, some are shorter e.g. platforms 9 and 10 which can only fit 8x20m suburban type coaches each. And yes, they do run peak time additional trains.
[1] There are two very long platforms, 1 and (I think) 15, which will take the Caledonian Sleepers, which other than purpose-built Eurostars are the longest trains in the UK.
