Do we all agree that in the end all we wanna get from working somewhere is primarily money and not experience?

Nope.

Money gets you through life, experience gets you a story to tell at the end of the road.

Definitely not always. So no, I cannot agree with this. The last 6 years I was in this industry entirely for the xp and skills. Fuck it, I even switched from sysadmin to dev for 3x lower salary just to get xp!

Now I'm in a place un my life where I need to save up €, where I have xp and skills, so now I'm to change my working mode from learning to gold mining.

So again, my answer is NO. Your proposed hypothesis is not always truthy.

Not always.
I pick up something to earn a fuck ton for a while, then take the rest of the year off to invest in experience. That experience is what I live for, but it so happens that the next time I'm off to earn, the experience boosts the income.

It's a not-so-vicious cycle.

It's money when you realize no matter what you do doesn't matter anymore...

Or maybe I have just given up.... I feel as long as I don't get fired, I don't care...

And if I get fired or need to find a new job, I'm fckd no matter how much experience I have since that's been pretty much the experience I have whenever I try to find a better job...

Primarily? Yes. Only? No! Sometimes it quite fun to solve real life problems.
