Presumably, you imagine that those who give of their time and pay their own expenses do not also put in hours at work to pay their bills and put food on the table?I don't work at foodbanks but I do useful work, fixing broken bikes. It may be not as noble in your eyes as a few shifts in a foodbank but to me, it's just as courageous if not more so. It's the putting your back in to the job, the hours, the days, the weeks, the years, the paying your taxes that count.
Is it only your personal wealth expansion and the continuation of that which motivates you? Frankly, I cannot equate the word, 'courageous' with the business of flogging and mending cheap Chinese bikes for profit. I guess it rather sums up your perspective on the elitist society of the UK - I'm all right Jack!
