Is it me or has rail travel become mercinary in pricing ?

STANDARD OPEN SINGLE from finsbury park in london to Falmouth : £128.00

The prices have been creeping up for years, but now its got to the point where you can fly almost anywhere in europe for less, than local train cost, beyond the 200 mile barrier. Fuel costs to falmouth in an effiecient car ? much less than £128 each way im sure, these train companys are mad. Theyre transporting large numbers of people in a purpose built vehicle and they cant do it cheaper than it costs to drive yourself there ? where has the efficiency saving gone in running a train ? Im sure if i were to buy £128 pounds worth of coal wholesale I could probably steam train my way to falmouth for the same money, these prices do not make sense.
