Why is there so much jargon in economics?

Capital, equilibrium, exogoneous, endogenous, dynamic, stochastic, factor endowments, returns to capital and labour, Heterogenous, the business cycle, the list goes on. Why can't economists just use much more suitable terms to describe economic phenomena?

Dig into tech, science, medicine, any form of maths and you'll find jargon. I've seen equilibrium, exo/endogeneous , dynamic and stochastic in Chemistry, biology and maths.

So they're just borrowing existing terms that they think best describe what they're talking about.

It's acronyms that are made up to sound good as acronyms and not as the most sensible name for something that get up my back, and the military seem to be the best at doing that.

If you dont understand any of the above terms that gives Financial advisors license to charge extra so they can work their magic they only they know how.
Sure it pays to have a financial advisor/accountant if you dont know your way around but it is no substitute if you learn a little yourself.
