Most major economies have been taking on increasing amounts of household debt, or are already carrying too much. That includes: Norway, Sweden, Belgium, Denmark, Finland, Switzerland, the Netherlands, France, Canada, Australia, New Zealand, Spain, Ireland, Portugal.
Others like Italy have taken on more debt (30% more in ten years), but started from a relatively low base. Or Japan, which has a bit too much household debt but has been flat for 20 years.
The US, Germany and the UK are among the few that have been actively reducing household debt.
In the US assets are richly valued due to the former QE and low interest rates, but there isn't a bubble (yet anyway). If the US continues to reduce household debt, while boosting employment and wages (the US unemployment rate is half that of the Eurozone), that will only improve the situation. The US will very likely substantially outperform its peers over the next decade; the strong dollar has reclaimed a lot of lost purchasing power for the middle class, effectively giving Americans a 20% pay raise versus the rest of the world (and that's before interest rates climb).
