The reason is Ken, is that if you've had probs in the past, but now you're good for the money (so to speak), it gives you a chance to prove it with a low limit, but higher interest card.
You're looking at 2 completely different products though. Vanquis/Capital One credit cards are aimed at people trying to rebuild their credit history & rating over a period of time.
Payday loans are aimed anyone who needs a short term, one off solution and are not meant as an ongoing fix. If they are used as such, then it's time to question how you are handling your finances.
