It is a slippery slope, yea, but there's a need for perspective, too. Even a lavish fleet of cars, let's say £3m worth, isn't going to put a serious dent into his finances, if that's the worst it gets with him. He's been a career-earning HW boxer for a long time, granted his paydays haven't been in the same ballpark as that one fight, but even from them, he's not going to be living the average man's lifestyle, not even close, and would have already amassed a few million.
Lavish compared to what though? Because that's the rub, for me; it can look like he's spending far more than he is by taking normal people on above-average shopping sprees and what not.
He lives in England, isn't in London and just doesn't come across stupidly decadent or out of line with what we'd expect of a 'celeb' in this country.
None of it points toward massive squandering as far as it looks from the outside, to me.
Even if he's taking them to lavish places by poor people's standards every week, he's blowing thousands and accumulatively 100's of thousands doing that, not millions.
And still, as far as I've known it, gypsy's are really shrewd with their money and bigger expenditure even if it looks flash and exuberant (weddings, funerals, do's) on the outside.
No doubt anyone could do with a top up or want more of a good thing, but that's not necessarily because they've blown their load... people like money and want more of it, typically.
