The evidence is inarguable that Australia is becoming too expensive and too uncompetitive to do export-oriented business. Africans want to work, and its workers are willing to work for less than $2 per day. Such statistics make me worry for this country's future. We are becoming a high-cost and high-risk nation for investment.

My mum and dad ran a family cafe in Sligo for 35 years and worked long hours. We grew up in a very hard-working family and had a lovely atmosphere, as we lived above the restaurant. It definitely made me want to work hard, whatever I chose to do. As the baby of seven kids, I was definitely a bit spoilt.
