Only if they somehow create a barrier to entry that doesn't exist today.
It's not impossible, but if they go into corrupt regulation (how else could they do it?) there is no reason they can't get the same without the throwing a lot of money away first. So, again, they won't.
I think the barrier to entry is inherent in the "rich people..." part of your idea. Industries that have a huge financial requirement in order to lay down the technologies needed have historically been the WORST monopolies (at least in the US, we have examples in Oil, Railroads, telecoms, etc).
Also, you make it sound like corrupt, industry protecting regulation is the exception and not the norm. Where do you live, and does this fantasy place accept immigrants?
