Currently the copyright term in the US is life-of-author plus 70 (edit: corrected from 90) years. Life of author has some reasonable basis. Past death it's understandable that descendants would want the estate to be worth something, if an author was unable to capitalize upon their work in their lifetime, but supporting an author's family for 3 generations is ridiculous.
There isn't a political solution to this. Because the US has a territorial electoral system, no politician is ever going to be representing a constituency who will care about the diminution of copyright terms as their primary issue, and building a legislative coalition to advance a nebulous public interest is hard, massively more so when countered by politicians who are bankrolled by large concentrations of capital.
In this country, any attempt to advance the current and future public interest over private gain is loudly denounced as tyranny by people who are awash in wealth and power. Those who try to undermine the foundations of capital from below are denounced as thieves and terrorists. That's why you get an endless ratchet effect.
