If the Directors follow your guidance, they have to double all the ticket prices!

Palace have - with exception of one brief period - never "threatened" to become a top division team. We are seen as occasional visitors to the PL. In order to build the kind of "big team" image/support craved by many here CPFC just have to stay in the PL and progress. Do that for enough years and we will begin to be taken seriously as a PL team and everything else will follow.
I appreciate easier said than done.

Well that's true if I was being harsh if have said the only 'big' London clubs are arsenal and spurs, but tbf in the current era chelsea are up there even though it's a bit false, and yeah, it's maybe a stretch with west ham, they aren't really. But still, whatever, like you said, a lot of us like it the way it is.

I can see why people fantasise about Palace commanding huge gates and the club having massive support round the boroughs etc, but it would come at a huge cost (literally and figuratively)

jesus, so the best ever Prem team from South London is the one which died, never got much fans and bVggered off to milton keynes ?

Yes, Palace are building a history and have been doing so since 1905. They reached a peak, so far, in the early 70s and have gone a bit backward since. Look at the evidence of the stadium size to the support. At the original Crystal Palace huge gates that whittled down a bit at the nest and the brief stay at Herne Hill Velodrome, but still good sized gates in that league. The move to Selhurst saw gates grow again and the subsequent ground improvement by the late, great AJ Waite saw gates really soar to at least 50% higher than they are now. Proof indeed the input of the owners is well reflected by the subsequent rise in support every time. Again, it's up to the board to show they have as much faith as the fans, or the club go the other way. To say Palace are not building a history, like all clubs, is like saying the top sides always had large support from day one. That isn't possible as much building support is.
