Humanity comes to the end due to marketing?

Recently i watched that video,after some minutes a horrible thought was spinning into my head.Imagine people stop walking and use this for simple and natural moving needs?I suppose that this will have a great impact on our body,and for what?Do we need to get rid of walking?NO.
Big coorporations lucks of ethical marketing technics,they do not point their investments to balanced solutions helping humanitys future rather than spending millions of dollars creating unnecessary gadgets which some of them my have destructive effects in our biological existance.Goverments have no role to that and this is dissapointing too,how do they allow poor citizens strugle everyday for survivor and the same time some basterds of moneymaking spend millions to junk and dangerous investments?
