You may well be right, although the suspected apocalypse didn't happen this year as many predicted and it may not happen next year either.
It is also quite possible that mortgage rates and inflation will begin to drop within 12 months and everone will be full of the joys of spring and happy to blow £1500 on Spurs once again.
I agree that the consequeces of inflation and increase housing costs will lead to many more tickets being listed on the exchange, which will probably mean more going unsold and them more considering dumpung their STs at the end of next season, unless things change drastically for the better both on and off the pitch.
