I'm on the "support" clan but still respect Showtime747 views which generally "bias" against FI/RE.

Oh.....I support FI, but not RE....
I think the main reasons people set their mind to RE is plain simple --> they don't like their job.
There are many studies on the reasons, like :
QUOTE
1. They are not respected as people at work. They are viewed as production units, rather than valued collaborators.
2. They don't have the right tools, equipment, information and basic operational requirements they need to do their job. When they ask for tools or guidance they get yelled at or ignored. What kind of company would impede its employees' ability to do their jobs, then get mad at them for asking?
3. Their employer disregards their personal life and has no compassion for their obligations outside of work.
4. Their immediate supervisor is a tyrant, unqualified for their job, or both.
5. They are tired of being lied to.
6. They have no visibility into the future and no confidence their leaders will do the right thing, either from a business standpoint or a human standpoint.
7. They are tired of dealing with the politics in their workplace.
8. They are underpaid and overworked.
9. They go to work every day and push a rock uphill, trying in vain to get forward motion on their projects. They're tired of pushing.
10. They have to watch every word they say and every move they make, because the knives are out and they could get in trouble -- or get fired -- for almost any reason.

Why some people don't like to work
So why do people hate work and try to avoid it?
Here are some possible reasons:
1) Self regulation problems: Some people have self regulation problems that prevent them from committing to most tasks. Those people usually start on something then shortly lose interest after they experience any unpleasant feeling while doing it. See Why we lose motivation after getting started
2) Fear of testing self worth: In the Solid Self confidence program i said that the fear of testing one's self worth can prevent so many people from completing a task to the end or even starting on it. This fear is usually unconscious which means that the person might have no clue why he is doing so
3) They are not ambitious: Work isn't usually interesting but if there is a reward then the person will get motivated to do it. Ambitious people always see a reward for what they do and this is why they get motivated. People who are not ambitious might not really care about getting anything done. See Why are some people so ambitious
4) Fear of taking responsibility: Sometimes behind the desire to avoid work is the fear of taking responsibility. This could happen for many reason. One example is the kid who was raised by an authoritative parent who scolded him every time he messed up in such a way that he decided to evade responsibility later on in life. See fear of taking responsibility.
5) They don't know what they want: When a person doesn't have a goal that stems from his personal needs then probably he won't be motivated to do anything. When a person copies the goals of others he will not find any motivation to pursue those goals
6) They borrow goals from others: Just like i said earlier when you copy someone's goals you won't find any motivation to pursue those goals since you won't have any real needs that could motivate you to pursue those goals
https://www.2knowmyself.com/Why_some_people...nt_like_to_workMany who set an early retirement target can relate one of more of the above to their job environment/personalities ?
At 40 years old, a worker is at his prime. He makes the most money at this age. He should be a senior already and well respected by the subordinates. He can contribute back to the company/society/economy/country. So much he can do.
Those who said after RE they have more time for family/charity/health/thing I like to do, are just giving excuses for failure in good time management. Those 4 things cannot be neglected at any age. They should learn how to improve on their time management instead.
