So what has happened to the 2 nations since the great crash of 2008 and who has come out better. Financial crises take a long-time to recover from and we can't be sure we are there yet, plus of course the US has not had to deal with the Euro collapse, which has probably benefited the US, but more of this later.
First up, let's compare GDP:
We can see from the above that firstly the US crash was worse and also that GDP growth in in the US has been stronger. In total, the US economy is now .12% bigger than 2008 but that the UK economy is still 3.5% smaller.
So on the strength of this the US debt fuelled recovery has done better than the US attempts at austerity.
But how about the Debt to GDP ratio?
