Opinions never are.
I once knew a married couple that had a competent FF body to shoot various things around them for fun, and then due to the struggles of having to share the body all the time and the IQ just wasn't up to the latest offerings, one of the newest and pretty expensive FF model is added to the bag, along with a rebel to combat some physical discomfort of shooting the FF, so that each of them can shoot with whatever made them comfortable whenever they wanted to, along with alot of lenses, some that overlap with each other. There didn't seem like alot of need generated all those purchases, but I don't judge them, they seem to be able to afford it and it made them happy.
I don't mind people being 'rich'. Every now and again in my life I've been 99.5% there myself and I may/will be again. Onwards ... upwards.
But it offends me when people spend money just to have that latest thing. Dammit .... if I just could have my hands on all that lovely filthy lucre, I could show those people how to spend it really well. Every last cent of it would be pulped and squeezed beyond all possible recognition!
I don't mind it when rich people spend money on extra/special stuff. I'm just embarrassed for them when what they are buying is only new ... but otherwise conspicuously without merit.
