He's not in government so anything he said prior to the election is academic as he's not in a position the implement anything.
I'm more worried about what Theresa May and her government will do to education, welfare, the NHS, workers rights, human rights and a host of other laws we took for granted whilst secure in the EU. Rather than being distracted by what Corbyn might or might not have meant we should be joining forces to stop this government from implementing policies that will hurt all but the very rich.
The magic money tree exists for this government when it suits them (e.g. DUP bribe) but remember it's not a real magic tree. To find money for the things they want to do they take money away from things most of us need.
