No more money
They're certainly united in telling us we're all going to be poorer for some time to come.
Last week Vince Cable pointed to households' record and arguably excessive debts (equivalent to 170% or so of disposable income) to explain why consumer spending can no longer be the engine of our economy.
Which is why as business secretary he is to an extent picking up where his predecessor, Lord Mandelson, left off, by arguing for industrial interventionism, or the use of scarce government resources to help exports and exporters (though not, he insists, through some kind of government-sponsored Britain's Got Talent for manufacturers).
As for David Cameron, he is today shutting down the other engine of economic growth, the public sector: a state that grew and grew and grew under New Labour is set to shrink and shrink and shrink, says the prime minister.
Yes, for the state as for the individual, frugality is necessitated by past profligacy - whose disturbing manifestation is the national debt rising by an unsustainable 11% of GDP per annum.
So debt is our problem. And its effects have been particularly painful for younger people.
Which is why I have made a new programme for BBC3 - On the Money, tonight at 1900 BST, clips here and here. It looks at some - by no means all - of the causes and triggers of this mess and discusses the implications with an audience of those at the start of their careers.
Some would say they have every right to be furious with my older generation - since it is plausible to say that the parents of today's young adults had more than their (our) fair share.
The argument would be that we undermined the foundations of the economy by borrowing more than we could afford - and it is our children who have born the brunt of rising unemployment.
And, if you see rising public sector debt as an inter-generational transfer of a future tax bill or reduced public services, it is younger people who will pay for the more generous state provision we've enjoyed.
And that's to ignore the prospectively massive burden for our kids of funding our pensions.
The insult added to injury is that all that household borrowing led to a trebling of house prices over the 10 years to 2008's peak - but the subsequent fall of 16% doesn't even begin to make homes affordable for first-time buyers.
Here's the funny thing. Those in our audience for On the Money weren't on their way to the barricades, as far I could tell.
They were strikingly optimistic about their personal prospects - and primarily interested in practical solutions to their immediate problems (such as how to avoid being classified as a poor credit risk - yes they want to borrow more).
One of the conclusions I drew was that the general-election campaign had not prepared them in any serious way for the public spending cuts and lean years to come.
So as and when the harsh reality of today's speech by David Cameron sinks in, the anger of youth that is conspicuous by its absence may be ignited (oh, and that pernicious disillusionment with our elected representatives - which is particularly characteristic of a younger generation - is probably not going to evaporate).
