Patient discussion about productivity

Q. Is it safe for teenagers to use weight loss products? This isn't an ethical question, but quite literally asking if it is safe for a teenager to use weight loss solutions like weight loss milkshakes and other things of that nature. Thanks in advance!

A. From health point of view- there shouldn’t be a problem if those products are safe. But from an educational view- the minute you start relaying on weight loss products to loose weight for you- you become lazy. Then you’ll loose weight and gain it back with some extra. You need to start acquiring good habits while you are young- balanced nutrition and sports.

This overall critique leads to a more modest conclusion relative to the author's: Wage legislation can lead to higher worker income, without reducing profits, on the condition that laborers work a larger proportion of their contracted labor time, and these increased hours of effort dominate their decreased neoclassical productivities. Even more restrictive however, workers' welfare increases only under the allocation condition that the marginal benefit of income exceeds the marginal cost of foregone leisure, whether off-site or on-site.
The number of man-hrs used when calculating the productivities shown in this paper included all hours worked and reported in the mine, and, in the case of underground mines, also surface man-hours, but do not include hours in plants, shops, and offices.
