I would have agreed with the guy if his point about more money = better games was actually true.
In reality the vast majority of publishers out there do not give us more for more, we get less for more. Games are progressively releasing buggier, shorter, with more reusable multiplayer focused content.
If on-disk locked content actually felt like something new, wouldn't be an issue yet it isn't, it is more often than not, cut, or just locked out content denied to us to force paying more money.
Personally I'd be fine with this practice if they had the decency to charge us $30 for 50% of a game or $45 for 75% of one but they don't, they want their full $60 for the half game and everything else on top. Instead, it's actually getting worse. Some publishers are trying to slip in increases in prices. Noticing more and more PC releases creeping over the £30 price point, some 32, a lot 35, even a few trying to push £39.99. We don't get better games for that, we get the same old same old, with ever increasing amounts of DLC to buy to get the full flavour.
Numbers might seem low/cheap to you funny foreigners so I'll add a little context: when in Philadelphia, I can order two large pizzas for $14.50. To do the same here in London, $45-50 depending on exchange rate fluctuations.
