Their wealth does not impinge on my wealth, and my wealth does not impinge on their wealth. My wealth will not change because of any change in their wealth.
That's where you are wrong.
The wealth of other DOES effect you.
Doubt that?
Then you must also believe that the market for investments is NOT an open bid system.
It is, so you are obviously misinformed about how capitalism and this economy actually works.
Some investments are open market, and some are not. Whether any market is open bid, or not, has absolutely nothing to do with my statement. Being outbid by a competitor has no impact on my wealth. It remains the same. Of course, the entity that won the bid may enjoy an increase, or possibly a decrease in its wealth. That doesn't affect my wealth either.
I retired at 55, virtually debt free, and with enough assets and positive cash flow to handle all of my needs and most of my wants. You can rest assured that I have a very good comprehension of markets, the economy, and capitalism. I grew up as a part of the working poor. I retired fairly well off, and all due to capitalism and the opportunities that it offers anyone willing to take advantage of it. I could have stayed active for another 10 years or so, and retired wealthy. I chose not to, because I had other interests that I desired to pursue.
