Probably mostly to amuse myself...
The concept is really simple -- most people get rich becuase they love what they do for a living. And they are good at it.
Nah, not really. "Most" rich people who build business that become big enough to make them rich, assuming that's who you're referring to here, have to put in massive amounts of hours and take a lot of risk. They also end up having to take on more responsibilities outside of what that one core thing they love to do is. It's highly stressful, time consuming and they often have to make a lot of personal sacrifices to make things work, like family commitments, marriages, etc. I'm not sure of anyone who would classify that as "fun." Some aspects of it sure, but not most.
And, as chance would have it, the things they like to do are in demand by others -- so they also are getting paid well.
See above. I'll give you the premise that some people invent stuff that other people would be willing to pay a lot for. But, just because someone invents something doesn't mean they automatically make millions on it. There's a shit ton of work involved filing for patents, copyrights, securing capital/manufacturing, developing marketing, business plans, etc etc. All that stuff is what i was referring to above as lots of hours, risk, stress and taking on tasks that these people don't really like to do. Someone who invents doesn't do business plans, marketing, manufacturing deals. They do that part so they can get paid.
Many other people have no such luck. They like to do things that others do not find all that valuable. Or they don't possess enough talents to compete with those who do. Those people have to work hard to earn a basic living and the money is the main thing that motivates them to work.
It's probably moreso the opposite. While most everyone wants to be rich, most people who have the capability to do it don't want to put in the effort that's required. So, they'll work 40-50 hours a week with relatively low stress and a comfortable wage that allows them to do many of the things they'd like to do. That's the American dream, dude. The lower skilled workers need to work harder and longer just to get to that level until they get more skilled and make themselves more valuable.
That is why the rich are so fortunate. And that is why asking them to pay higher taxes is only fair.
As laid out, your premise is total bullshit. The only rich people it really applies to are lottery winners. Even entertainers and athletes work hard at their craft in order to get where they are despite the fact that was they (presumably) love to do is something that people will pay a lot of money for.
I'm not even getting into the whole "what he/she loves to do is more valuable than what he/she does so it's not fair" argument. I could be the best person in the world as making monkey noises and i love to do it. Just because i'm the best and i love to do it doesn't mean anyone is obligated to pay me to make monkey noises all day long. If you want to say that i'm unlucky for being able to make uncannily accurate monkey noises instead of being 7'0" tall with a 42" vertical then fine, but such is life.
In my world, you try to make the most of what you've got and appreciate the things to do have, not focus on what you don't have and resent others because they have it.
