If only that were the case. As usual, let's go with the car analagy. A person gets a ticket for speeding. That may slow them down for a week or two, but they will enevitably be speeding again when they are in a rush, or old habits take over. Fines are a slight deterrent, but they are in no way the most effective discipline method.
Now, on to corporations. They are trying to make money. they want the lowest price. In fact, they are basically required to get it in most situations. They are told constantly by their investors that they need to maximize shareholder value. That means doing the most with the least. Actually, this doesn't just apply to corporations, here in America, I work with bidding to a lot of schools. I may do far better work, but if my price is $10 over the other guys, he wins, and does his shoddy install. This is maximizing their "investor" value (taxpayers).
They are certainly not going to fund their own internal small web development team. Let's add up the prices. Let's say there are 2 people in it and a new manager. We'll say that the two devs make $50K/year, and the manager makes $60K. Then we tack on $25K per person for taxes and benefits. That's $185,000.00 per year for team, every single year. No way is that going to fly, if they only get fined $250,000.00 once per every 10 years or something.
So, no, fines will not change things in corporate culture. It is a nice dream, but a dream nonetheless.
