What has been the impact of economic growth on employment hours and wages? In fact, work hours are matter a great deal for the incomes of poor group of households in developed countries, such as United States or United Kingdom or developing countries, such as Hong Kong, China etc. countries. For example, HK economic growth has a large influence to raise employment hours more than rising wage levels, such as HK general working hours are risen up to 10 to 12 hours or more per week working days to low income level of households, but the low income level of households group has not been rising wage level generally. So, I feel HK economic growth could not give any benefits to the low income level of households, such as without reduction employment hours and without raising wage level to the low income level of households in HK. Also, HK's economic growth only raises many jobs supply in HK society. Otherwise, America economic growth can give benefits to low income level of households, such as reduction employment hours, rising wage level to low income level of households and raising jobs supply in America society. Hence, the developed countries, such as America, England which economic growth can give more benefits to low income level of households. Otherwise, the developing countries, such as India, China, Korea which economic growth can not give more benefits to the low income level of households and these developing countries will cause disadvantages to this low income level of poor group in society. It is possible that the developing countries' low income level of households often need to increase to spend more working hours to assist whose employers to develop whose employers' business, due to their employers do not want to increase to employ extra workers or staffs to assist whose business development, who need whose current employees to raise more extra working hours to work to raise work efficiency when these developing countries are encountering the economic growth stage.For example, HK employers do not concern moral issues about abnormal working hours influence. The outcome is either Hong Kong labors work long time working hours abnormally who can not rise Hong Kong economic growth or who can rise Hong Kong economic growth in long time. Generally, Hong Kong employers choose to pay less salary expenditure to need many extra labors to work abnormal working hours to help them to rise productivity, but who don't concern that long time working factor will influence unhealthy to current workers due to who need to work long time working hours abnormally in long time and it seems to cause their workers will reduce productivity and inefficiency in long time.
