Profitability does not necessarily correlate with better life for customers, it all depends specifically on the subject.
Averts are entirely set up from the point of view of businesses, people can live better without ads, businesses need them because another competing business is also doing advertisement, it's just an arms race. Advertising and its growth is a cancer in our society, it destroy society values just for a quick buck and provides zero value to our society. I can't wait to see that die. I can't believe some of the smartest people we have out there spend all their lives making people click on ads, this is totally insane.
Advertising is just oppression by private companies, I don't see any difference with government ads. Except that because there is a profit in private advertising, it's even more invasive and everywhere.
