Spot on mate.
A lot of teams have 'shown ambition' and 'speculated'. e.g. Gretna, Livingston, Airdrie, Dundee, Hearts (they might be 3rd now but there's an administration from the 'speculation' years to consider), us under Boyle and Nevin. There must be more that I'l missing, but I don't recall a recent story of a team in Scotland ploughing loads of money into a team, being mega succesful and becoming financially viable from their investment. There is no money to be made in Scottish football for anyone outside the uglies (and look at the financial state one of them is in). Even in the EPL, the sucessful teams are making massive losses and have 'donors' throwing hundreds of millions in which they'll never see again.
The path we're on is the only viable one and to my mind, thats why any 'investment' needs a hell of a lot of scrutiny before moving forward.
