I wouldn’t mind it for that reason. The Red Cross do good work that need to be financed.
Here in the Netherlands they do that by contracting out volunteers for first aid services to events like fairs and runs. The volunteer donates their time, gets trained for free, the Red Cross gets paid by the organiser and makes money for their mission and an small army of experienced first aid people and EMTs to help out when disaster strikes.
I’m such a volunteer and it’s a great distraction from my normal job. I also get to use my skills outside of the Red Cross, e.g. as an action medic at protests.
Cool sidenote: there’s this network any CPR certified person can join to get alerted by emergency dispatch when CPR is needed close to your home or work. This has helped massively to get CPR started within 6 minutes mostly anywhere in the country, even when ambulances can’t get there that quickly.
