Spain: Myth:*national debt is a burden that will ruin our children’s futures
Argentina: Myth:*national debt is a burden that will ruin our children’s futures
Germany: Myth:*national debt is a burden that will ruin our children’s futures
Spain and Germany aren't currency issuers, they're currency users, which is a different ball game. This is one of the problems with being a member of the Eurozone. EU countries operate more like US states in this context. If these country could still issue their currencies, they could have spent in a counter-cyclical fashion in we wouldn't have the problems we now see in Spain, Portugal, Ireland, Greece and Italy.
Argentina pegged the peso to the dollar which was not a wise move.
Again, at the risk of sounding redundant, in economics such a concept doesn't exist, whereby we sacrifice today's output to some date in the past, and then roll it over to generations before us. Therefore, in real terms, no such burden or share of debt exists for individual Americans, our children or grandchildren. Our children and grandchildren, just like you and I, will be able to go to work and produce and consume their real output of real goods and services regardless of how many bonds need to be rolled over.
