Global crisis: Obama imitates losers

Here is a chart showing that the economic crisis of 2008 was 1) global and 2) worse in other countries than in ours. Megan McArdle argues that this shows that blaming Bush or Obama for the terrible economy of the last four years doesn't make a lot of sense. However, it is worth pointing out that almost every major policy change of the Obama years has made our policies more like Europe's. If we did better than they in the global economic crisis, why is the Obama administration using the crisis as an excuse to move our economy in their direction? If the economies with more controls, welfare spending and regulations did worse during the crisis isn't that an argument against those policies?
