I beg to disagree with this publication, it's their view but it doesn't matter if you are working in the office or at home, all that matters is to get the job done and be gainfully employed as a citizen of a country. In that way, you will be able to live the good life you desire and will also be able to transact financially among other people in the country which is what encourages the economy.
No, no, that statistics is actually true and I'll explain why it is true. When you are at home, you are more relax than in your office. At home, we all have habits of drinking beer, watching TV, doing some random staff, home is a very different area where we were always relaxed since our birth. Also, if you are not alone at home, it's very hard to keep your attention on work because parents or siblings will sometimes call you and or attach you some duties. That's why a lot of people that I can confirm from my personal experience, buy a membership of special co-working office spaces to feel the atmosphere of the working environment, be more focused on their work and less destructed by others. Definitely, it doesn't apply to everyone but it's true for majority of people.
