(I'm going to assume you're either European or referring to Europe by your snark; we'll just set aside definitions of developed as something we might fundamentally disagree on.)
Critically: the US has an overall population density 1/10 that of countries like Germany. If you can't understand the impact of that, you're not paying attention. Further, the US doesn't have draconian commmunity laws that compel people to only build new homes within town limits, as some Euro states do. (Making the effective density of populated Europe much much higher.) If you buy land in the US, you can usually build a house on it, whether you're in a town or not. Ergo, the ability to quickly/cheaply stretch power to remote locations has more value here. It's a tradeoff that people make in their home choices, whether they recognize it or not.
In places like cities, where population density warrants it, yes, the power cables do usually go underground.
If, as the op asserts, it's an ongoing problem regarding the major lines that feed the municipality, then eventually the municipality will address it with their local utility. If the OP has such a problem with it, and is sure everyone else does, I'm sure it will provide a firm point for them to be elected to the city council to fix it. Or wait, was he not actually looking to get off his ass to FIX the problem, just whine about it?
