I sadly suspect this is part of the reason. They have more money and chose a Mac because they are educated and can get a decent salary and mentally independent enough to make a conscious purchasing decision.
If you just obediently go with what the trustworthy computer salesman pushes at you, you end up with a Windows computer. And obedient trusting people are what the scammers want to target.
I'm going to have to disagree with that. I know plenty of people (with money, yes) that want to "get a Mac". There's no mentally independent purchasing decision, it's just what other people have, and they look cool.
As it happens, it's a good choice. But it could easily not be, and they'd still do it.
Notice that they are saying "Windows support" not "Microsoft Support", not knowing that Windows is a product from Microsoft would suggest they are looking for people with a very low level of knowledge.
I'm guessing retired people who have a good pension coming in.
OTOH that must put an upper limit to the amount people are willing to spend to get their computers back from the scammers. If you only paid $300 for a PC from wallmart you won't pay more than that surely.
They do this to avoid being cornered. On one occasion, when screwing with one of the callers, I had a little rage fit accusing them of breaking all kinds of laws. The "manager" informed me that "We never claimed that we were calling from Microsoft, we're calling from Windows Tech Support, which is the name of our company." The agents are very careful not to say they're calling from Microsoft. I suspect that this is some attempt at circumventing exposure to local fraud laws wherever they are based. I'm not saying it will be effective, mind you; just that I suspect that's why.
The target audience is for the non-tech savvy. These people, I imagine, are people who spent very little on a PC/laptop, most-likely running Windows.
So, I wouldn't break it down by who has more money, but by who they are more likely to get money out of.
That's perhaps one of the reasons this scam can be so effective.
Education and money don't necessarily translate to domain expertise in everything.
I don't have to tell you that Macs aren't immune to viruses, just that they're targeted less. Like malicious software, there simply aren't enough Macs out there for the scammers to give a shit about, yet.
You don't go trawling in your garden pond when you live next to the Atlantic Ocean.
I don't doubt that, but you can't really refute a general argument with a single data point. It's not as if I said "all Mac users are more intelligent than all Windows users", which would be nonsense.
"Women in IT are generally paid less than men." cannot be refuted by "I know a lady who makes a ton of money in IT."
You first bub.
Edit: and frankly, I don't see how you're refuting my point that being intelligent and educated doesn't necessarily make you a domain expert in fields you have little experience in.
Or are you the kind of guy who lectures the mechanic with 30 years experience on how to fix your car?
