Most people who say owning or investing income is the way to go started out with the means to make this obtainable in their life. Not saying you can’t work your way to that, but you will have to work hard to get there if you aren’t from circumstances where wealth is available to you through non-labor means. I find the majority of the people espousing this ethos the loudest are the “born on third base” types. They have a real need to justify their wealth as “earned.”

I think it’s likely aliens exist, but unlikely any alien species will be what we expect. I highly doubt we will see humanoid “little green men” or anything like the majority of science fiction portrays. Each planet is vastly different in just our solar system. The vast differences in environments across the galaxy will yield vastly different paths of evolution. We are only looking for “life” that fits our narrow definition based on Earth’s species - we have likely already missed signs of alien life.
