timppu: Yes, unless Ricky relocates to some other country because he didn't agree with the way the earlier governments borrowed money.
In a similar vein, Ricky probably benefit in many ways back when the government borrowed money, boosting the local economy. E.g. if Ricky owned an apartment or house, most probably its value increased. Or he enjoyed better services, or he got more clients for his business from the domestic market (as people had more disposable income overall), or maybe he or someone in his family even got a job in the public sector?
Your original question seemed to be "is Ricky morally responsible?", but now I feel that is the wrong question. The real question is whether or not Ricky is affected by the (good or bad) decisions made by his government? Yes. If his government was stupid enough to spend so much money that got the whole country to problems later on, he will feel the sting too one way or another, unless he escapes it to some other country.
The fact that there is at least a theoretical possibility to escape it all dilutes the idea of any kind of "moral responsibility". If there really was such a "responsibility", then surely it would follow you even if you moved abroad with your belongings, right?
I don't quite understand what you're trying to get at anyway. Are you saying that it is ok for citizens to benefit from good decisions made by their government, but not suffer from the bad decisions (without relocating)? How does that really work out then? Isn't it only fair that they are equally affected in both cases?
If I perform a service to which you have not agreed and did not want, should you have to pay me for it? Does it matter whether or not you benefited in some way from the service if you did not consent to it?
Contracts derive their legitimacy from our voluntary agreement to terms. Is the national debt a legitimate contract? Does it have the consent of those responsible for its payment? Is the concept even compatible with democracy?
Each generation of citizens decides for themselves the amount of taxation they will tolerate, and most of us more-or-less accept democratic process as a sufficient means of resolving this decision. But even if we grant the legitimacy of taxation itself, how can it be just for a generation of voters to reduce their own tax burden at the expense of future generations who will have to suffer the consequences?
And what of those in the current generation who object? Taxing Ricky is one thing; his money is taken in a straightforward fashion, and his choices at the ballot box are clear and their results obvious: To approve current services and their consequent taxes, or vote for lower taxes and reduced government spending. But if a government can accept debt on behalf of citizens, hasn't that vote been significantly weakened? What had been an effective check on the size and scope of government is now irrelevant in practice; a demand for lower taxes can be met with more borrowing. Spending continues unabated and citizens are still on the hook. What's more, the entire issue is much less comprehensible to the average voter, and they are shielded from the consequence of their vote (by transferring their tax responsibility to future generations).
There are some things for which "the consent of the governed" (i.e. the whim of the majority at a particular time) is not sufficient justification. This is why individual rights are so important, and this issue has me thinking that some kind of explicit "right of the people to be secure against indenture to debt on behalf of their government" (perhaps with a caveat for defense: "except as regards the defense of their sovereignty") should be codified in our constitutions. This would force an honest rate of taxation to meet spending and wake people up to the true costs of their out-of-control governments.
Re: "move" or "revolt"... There's a lot to be said there, but not by me, at least not now. I need sleep. ;)
Brasas: but the OP certainly is indicating he is willing to let the government default on its debt implying the citizens should wash their hands of it with clean conscience.
I didn't start the thread thinking about default as the preferable option... but yeah, I suppose I'm leaning that way to some degree as we explore the issue. I resist the conclusion because I do think that we should keep our word and honor our contracts, but... well, see my reply to timppu above. The question becomes whether it is better to default or to balance the budget, pay the debt, and make constitutional changes to prevent this from happening again.
