$1500/1920 work hours a year = $0.78/hr. Seems reasonable to me.
Meanwhile you have things like ad campaigns that have "unlimited" budgets. Hell, there's tripling staff size in a year without some matching revenue growth!
Chairs don't kill startups.
If that sounds good to you, consider $150/1920 instead for a thought experiment! Sounds about fair for someone like me who assuredly could work for years on end sitting on a rock or any random plastic chair outside Hanoi for all I care.. I'd be madly paranoid about spilling coffee or such sitting in a 1500 piece of furniture
I'm not willing to compromise on my health or my working conditions. Too old for that. Spend money on things that make your life more comfortable or easier when you can.
