That's all well and good, but those 150,000 people didn't register for a job opportunity. They registered to see themselves on TV. There are opportunities for apprenticeships, corporate and personal coaching, etc, every day. You just have to have the chutzpah to go out there and grab those opportunities yourself, not wait for a TV production company's runner to hook you up with the coach on STV's bill.
As for Sandra's background, I am sooooo tired of the Scottish syndrome of competing to see whose background is the poorest, least educated, most deprived, etc. In the US people compete over who has the most education and memberships, in Scotland they compete over who has the least, which leads to supposedly intelligent managers insisting they grew up on the 108th floor of a tower block in the Gorbals with no electricity, running water, or lifts, so they ate bird droppings for sustenance etc etc. Any grown adult manager who can't get over their childhood should go back to the nursery.
There are lots of people doing what the producers on that show are doing, every day, but they don't spin it into a televised competition. I should correct that and say that they try to do it every day, despite the real "I kent yer faither" attitudes above and below them. Let's give those people the support and encouragement they need, even if they're not interested in televised spectacle.
