The reality is that easy money is hard to come by. The closest thing I'm aware of to that (other than inheritance, winning the lottery, or marrying into money) is to have a passion that matches a high-paying career.
This is something I didn’t realize until a much later age than I should have—or didn’t want to accept. I spent years in the public sector applying for corporate jobs for which, save for a connection I didn’t have, thinking that once I got in the door of major corporation X, once I got in the door I would quickly rise to the top, not that I had any qualifications to do that, and, even if I did, not as if there wasn’t competition for that top job from equally qualified individuals, if not more so. And I wanted the job purely for the salary and perks. I had this fixation about General Electric, and, amazingly, despite what I stated, above, I am sure I couldn’t have botched it up as much as long time Jack Welch protege Jeffrey Immelt did!
I grew up lower middle class in an area where there were many trust fund babies. I wasn’t one of them, and, at best, was treated as not one of them. I had this mentality, seeing that for many of them, their finest accomplishment in life was graduating from an Ivy League institution with a C average, usually after being on suspension for bad behavior or bad grades, or both, a few times. I thought, coming from a town of a few thousand, I could return wealthier than most. It couldn’t be that hard. It wasn’t until later that I discovered, through the internet, how big these fortunes were. Fortunes obtained with no regard for regulations, monopolies, and prior to an income tax. You can’t compete. Stuff like GE, a sugar monopoly, Crayola crayons, Remington firearms, all 19th century wealth.
My parents told me that wasn’t the real world. I didn’t want to believe it. I saw folks who never had to work a day in their life have incredible money and I reasoned if I showed up for work every now and again, that’s all it would take. I recall being about 13 or 14, in a rented house, which, after you paid the rent and put food on the table, there wasn’t exactly a whole lot left over, I had the audacity to ask my parents how much is in my trust fund and when does it kick in? Still, over 40 years later I know my father is resentful I had the gall to ask that. (Likewise, I still haven’t quite recovered from the shock of the response I got, LOL, that being zero and never).
Of course you have no way of controlling this, but the very best way by far to achieve an income is by inheritance. The stuff my parents, I, and probably many on this forum had to worry about was a non issue for these fortunate individuals.
