The people who own the club do have a lot more money than us. But they have also bankrolled the club's losses for over 20 years on the basis that eventually the club will become profitable. Fans showing their support - and lessening the increased financial burden - during a difficult time like this is likely to be important in their decision on whether to continue to support the club.
Also, the revenue that the club gets goes towards paying the salaries of the non-playing staff, who for the most part even less than many of us. The more money the club can make, the fewer of job cuts it will have to make.
As anyone involved in community rugby knows, the job cuts made by the RFU have been horrendous. Its revenues have fallen off a cliff. The fans who have been able to donate have helped Quins avoid that sort of drastic action.
