Sure, it's nice to be able to make a living from open source based on donations. That doesn't have to be comparable to Silicon Valley salaries that are fueled by huge ad money and other dubious sources. I know many people here are from Silicon Valley so they might even think it's a low salary, but I'd ask you guys to get some perspective.
If I know my donation would be used to fund someone's (in my eyes) incredibly high salary, I'd prefer spending it on somewhere where it would have more impact. You know, people who are actually struggling to make ends meet.
