Is it true that succeeding in a secular career that offers power and prestige leads to lasting happiness? No. Remember that the craving to control others and the longing to be admired are the desires that enticed Satan, but he is angry, not happy.
Let's be real here. This is in support for their anti-college view.
There are about 400 people who work for my company in my office building (it's an international company, but we have a big office in my city). Roughly 90 percent of the employees here have bachelor's degrees (including most of the administrative staff). About 40 percent have advanced degrees (master's or higher). Do they think we all get to control people? Do they think we are all prestigious? The vast majority have no interest in any of that. What they do have an interest in, though, is taking care of their families financially.
To be fair, I don't know how much of this is coming from a deeply cynical place and how much of it is just a product of sheer ignorance. I grew up in a Spanish language congregation full of immigrants and didn't really ever interact with any college-educated JWs. I remember when I was around 18, I met a recent JW convert who had a two-year associate's degree. Man, I thought that guy was something else. He had an associate's degree! I used to talk him up all the time and he'd be visibly embarrassed by it
Maybe these dingbats know so little about the real world that they imagine everyone out there with a college degree is living some kind of luxurious hedonistic lifestyle. Spoiler alert: Most people with college degrees are barely earning income above the median.
