I've been indecisive about the ENIC in or out debate, but had the overriding thought that they have reaped in the money without spending beyond our means, with all the attendant frustrations that brings to us supporters over the years. In defence of that, personally, I don't want to be a club that spends the most - I quite like being the smallest of the so-called big clubs, if that makes sense.
However, that 'policy' seems to have now put us in an even better place financially, with certain other clubs having major issues. However (again), Levy et al couldn't have predicted FFP/PSR so their financial prudence in getting us to this position is one of luck, I guess, although being financially prudent will usually provide good things in the long run anyway, and be less due to 'luck'.
However (again, again), let's not forget that we were ESL-bound, and Levy must have known the fan's feelings on this before he signed up. Even if it wasn't the majority of fans (and we'll never know that for sure) he made a hugely unpopular decision only reversed because he had to. But the key thing is that he was for it first and foremost (the whole ESL debate thing is another issue not for here).
So, is he / they trustworthy? No, absolutely not but with the caveat of be careful of what you wish for, grass isn't greener, etc, and all the other clichés that go with it.
Edit: finance is probably one of things I know least about so I realise that I can be over-simplistic on such matters.
Levy's on record talking about this football bubble bursting and the current level on spending not sustainable tbf. I think he's been planning for this for a while.
