A few weeks ago the task was to buy stock from a warehouse, sell it, and then reinvest in products that sold well. Now this was how Lord Sugar started out and is a module used by every person with a market stall. Buy, add a profit margin and sell. This is something most people can achieve with just a bit of effort.
However, the majority of the tasks are unachievable for the average individual. I loved Fast Food Chain - because in two days they decided on what they wanted to sell, designed and got the menus made, conceived a whole brand and a physical shop was made. That is not realistic for an average person. For a turnaround like that serious money is needed. Also, in earlier episodes where products have been pitched at major shops this again is something the average person can't do. I don't just know the head of buying at Selfridges, but Lord Sugar does.
So yes, having your own business is achievable with guts, determination and perseverance. However, it takes time (or a lot of initial investment) to achieve the financial success the team members make in days.
