I agree of course. My only point is that having a third Sugar Daddy club (Newcastle) won't lead to an uncompetitive league.but I don't think replacing one or two dominant forces with a sugar daddied ultra dominant force is the answer, to those leagues either.
Pre-Roman (so the first 11 seasons), the Prem had 3 different winners and 1 of those was a sugar daddy side. Post Roman (17 seasons), there's been 6 different winners. It got more competitive with the addition of side who could compete with Man United.
5 different winners in the past 8 seasons as well. The Prem is probably the most competitive of all the "big" league.
