I think you're right.So should I weigh in? if you support two teams...
I honestly don't care as long as the ones who go to the game are alright. It must be different for those, who like me, grew up around the area. Everyone was either Woolwich or spurs. There must be a different connection. I am being diplomatic not saying it is better just different.
When I was a kid and only went two or three times a year, I was so excited by those games even if they were the shittest games imaginable (end of season games when we're already definitely finishing 10th, early rounds of the league cup etc). Now I would go out of belonging and duty to those games but with only a fraction of that initial buzz.
It does change when it becomes a constant part of your life. Not saying fans that don't go aren't fans, but it's not the same. Some of the feelings we go through are all the same but some are different. I think the more you go the more of an attachment there is to the club. It's like a relationship, as you get older and grow together, in some ways it becomes less exciting but the bond gets stronger.
I think growing up in the area, living there, or having roots there, changes the nature of the attachment as well. That's why I could never understand people who wanted us to go to Stratford but if you don't have ties to the area then you might feel differently about that kind of thing. Having said that there are people from miles away who still regard Tottenham as a spiritual home and would always support the area not just the team.
As for the money yes it's a lot if you're hard up, but look how much cigarettes, takeaways, restaurants, alcohol, drugs, clothes, going out, holidays etc cost. A lot of people who watch Spurs cut down on other things. The far flung trips are expensive but for me they often act as holidays as well. Luckily my wife likes travelling to the likes of Azerbaijan.
For me I've found my level which is pretty much all the weekend domestic games, plus one European trip a season, maybe two if we go far. For some that's a massive commitment but it's only a fraction of the commitment made by others. When I've gone more than this I felt as though I was giving more than I was getting, it wasn't a good feeling so I cut back, it's nice not to wake up for work feeling knackered because you went to Sunderland the night before. Let alone travelling to Australia for friendlies etc. At the same time I don't know what I would do on a Saturday/Sunday if it wasn't for football.
