I think this builds straight upon her method, which she said could be improved herself so...

I’d say that has more to do with the regulations in place that ease the movement of goods and people. In that framework having the same currency and wildly different economies actually goes against the interests of your workers too, because it allows companies to outsource labour to other EU countries where the cost of living is radically less, with basically no drawbacks. The solution to this should be a consistent effort to strengthen the weaker economies, but more than anything impose similar taxation policies throughout the EU.
