"[In the United States of America] the elderly, who have the most to spend, get to spend the least of what they have on everyone else, and everyone else has to pick up the tab. ... The American Association of Retired Persons, founded in 1958, [is now] one of the biggest and most powerful lobbies in American history. It ... has an annual operating budget of nearly $2 billion, nearly ten times that of the National Rifle Association. (p. 10.) ... [O]n current trajectories Medicare and Medicaid look like they could soon bankrupt the federal government. ... Moyn [writes that] the solution to the problem of gerontocracy in America is the expropriation of the assets of older citizens who have far more than they need. (p. 11.) ... [T]his is an argument for socialism. ... Old age is naturally semi-socialised anyway. ... Gerontocracy in America is rooted in the unequal distribution of political influence. The money shores up the power and the power shores up the money. ... Economic inequality is exceptionally difficult for democratic systems to remedy in the absence of a massive structural shock [such as] war, revolution, famine, plague. ... During the Second World War income tax on higher earners in the UK reached 98 per cent and taxes on excess corporate profits were at 100 per cent. [T]he postwar Labour government, though effectively broke, was nonetheless able to construct an extensive welfare state, including a national health service, that persists in some form to this day. [T]he rest of the [21st] century looks wide open ... to the possibility of ... upheavals, whether geopolitical, climatic, technological, biological or something else." (p.12.)
