Other people's money
The phrase other people's money is commonly used in two ironically contrasting ways.
The original usage, which was common as early as 1914, referred to the investment banking industry. In his book Other People's Money And How the Bankers Use It (Wikipedia, text), Louis Brandeis (who became a Supreme Court Associate Justice two years later) sharply criticized the often-destructive uses to which investment bankers put the money entrusted to them.
Socialist governments traditionally do make a financial mess. They always run out of other people's money. It's quite a characteristic of them.
The phrase in this sense has become widely used as a criticism of "socialist" policies, even those promoting social welfare within a capitalist framework. The argument implicit in such usage is that social welfare programs serve only to take money from those who have it and give it away to others who then squander it, eventually depleting the original source, and do not otherwise benefit society.
The Thatcherian usage is ironic in that the phrase is being used in support of capitalism versus "socialist" programs intended to do social good, while the original usage was criticizing the excesses of capitalistic practices and the harm they do in the name of profit.

We haven't hit that point just yet, but we have hit our nation's legal credit limit of $14.3 trillion. To avoid defaulting on our loans, policymakers must raise that limit.” ...so that we can continue borrowing other people's money.

To his credit, the $700 billion military budget is the second item he mentions ("growing entitlements" are, of course, first), but then he immediately proceeds to ridicule a series of absolutely trivial expenditures, the largest of which is 0.0002% of the $700B originally mentioned and most of which are probably quite worthwhile investments of public money (including the bicycle helmets, which probably save money overall).
