If you have money, you can live almost any way you want in this world. You don't need to save humanity. You don't need to care about what everyone else thinks or does. You can just do what you want to do and have a good time.
Seriously though. This is how people without money think.
Dreaming about sitting around, jerking off, watching TV and playing WoW all day sounds a lot better than it actually is.
It is true that you can be a selfish twat and look out for #1 till you're in the grave. That's generally what all societies call a leech and would like to get rid of. Of course, you can make contributions along the way, or perhaps your entire selfish motive included the most philanthropic thing ever in existence.
Of course, when establishing the moral/ethical value of a person's life, you can look at the intention, action, and the consequence. But anyone who has psychologically matured into adulthood knows that the most weight falls upon intention, but not solely.
Once you achieve the basics, then you go after monies for long-term security. Then you will find yourself thinking about things like "meaning, contribution, art" and things of a slightly abstract or transcendent nature, because you're a grown up. You've grown as you've achieved success in the system you live in. Talking about some OTHER system ain't gonna get you there unless you can conquer the one you're in and use it to propel things forward.
You can't just reject the reality you live in and log-out. You have to embrace and expand, transcend and include. THEN maybe you can talk about getting rid of some shit or starting something new.
Life is short. There is no guarantee you will get out of bed tomorrow. Trying to change the course of world events (if you even could) is a multi-generational project.
For mere mortals, it takes several generations. But we've had some boss ass niggas on this planet who make this statement 100% null and void.
