Cost is high due to the high cost to FOM to be on the calendar and a lack of government subsidies, lots of other races get a big hand out. Its rare for this race to do much more than break even. Silverstone relies on the halo effect of the F1 race to improve sales of track days and other events so this is tolerated.
Ticket prices could come down if they could dramatically increase capacity, but that requires a lot more casual fans wanting to go, which requires a British driver directly challenging for the title and the circuit with its surrounding roads/parking being enlarged. Parking is better than the bad old days but its still not suitable for double the current capacity.
Lowering prices for anything other than seat fillers means operating at a loss, they cannot afford to do so for more than a handful of seasons.
