What with low-cost food imports and now today's debate on the role of nuclear power, I have to admit to wondering if the bubble is bursting on our indulgent lifestyles.
Only last week I was talking to a friend about "our generation" (I'm 35) - our use of cars, as much food as we can eat etc - and couldn't help wondering if in another 20 years' time we'll look back with affection at how easy it all was.
How reliant on others will we be for "staple" commodities such as food and energy by 2030? How vulnerable will that make us?
For years, farmers have been told that the self-sufficiency arguments for food production are outdated - something David Miliband reinforced recently. And yet at lunchtime today, the PM has cited our declining self-sufficiency in energy as a major concern and the reason for his backing of a UK-based nuclear solution.
Only two nights ago I sat in on a public screening of Molly Dineen's Lie of the land documentary followed by a Q & A in which one of the featured farmers in the film, Glyn Pearman, admitted to being embarrased that he could make money out of rearing pheasants "for the leisure industry" but was not able to do so out of beef and corn. "Somewhere, somehow, the priority is wrong," he said.
But further east, China is pushing an ambitious plan to be 95% self-sufficient in food. They seem to place as much priority on feeding the nation as fuelling it.
Meanwhile, as I write, a colleague has just turned his nose up at an in-house competition offering a prize of £50. We could all probably think of a time when we've done something similar.
So what value food? What value energy? Can we continue to be so indulgent with our lifestyles that we take these two key elements for living for granted? Perhaps we don't know how lucky we are.
Maybe the bubble won't burst and things can carry on as they are. Or perhaps the good times just rolled by.
One thing's certain: Our children won't thank us if we can't work out which it is.
