Difficult one we all love a bargain. So people buy stuff from the interweb instead and even if people don't buy off the interweb they at the very least shop around a lot before they buy things. So as a retailer how do they hope to get a decent margin. They then cut the margin which has an impact on wage levels. It's a viscous circle. Low wages mean that people that are genuinely enthusiastic and knowledgable end up keeping it as a hobby rather than a job where they can pass on their knowledge and enthusiasm.
