We're not like. There was people arguing that a club of our stature should be a more attractive purchase than a Prem club due to our low asking price (in comparison to the hundreds of millions of say NUFC).
Just to get to The Prem from our position you'd have to potentially spend £100-200m in the Championship for promotion (if and when we're promoted from this division). Even if there was a willing spender, not sure how a club like SAFC could stick within Financial Fair Play and do this when we don't have the Premier League money coming in, although don't know much about FFP.
Then once in The Prem you'd be looking at spending another £100-150m to try and just survive relegation. That's already ~£300m (if not more) including the asking price. To challenge for consistent top 10 you're looking at another few hundred million. An owner could spend all this and there's still no guarantee of success for them.
It's just not that attractive to buy a League One club. That's why we don't have a long queue of rich and successful buyers. You could argue that a few clubs have gone against the grain of spending hundreds of millions and being successful but there's very few in a long list of clubs.
