It seems kind of primitive to have power lines just hanging on poles, right?
Bit unsightly too
Is it just a cost issue and is it actually significant when considering the cost of power loss on society (work, hospital, food, etc)?

Heat dissipates easier in open air than in conduit, meaning the conductors can be undersized drastically compared to if they’re in conduit. Ever notice how the wires from the weatherhead are 2/0 awg, and on the poles and to your house (even after the transformer so same operating voltage), are way smaller? More like 12 awg on poles? The cost for the larger wire buried underground would be massive.
Also, as others have said, maintenance is significantly easier.
Yet almost all of the developed world does it…
