I know of absolutely no brokerage firm that will tell you to go ahead and buy a house or a boat based upon your stock return. That is not what it is for or how it is used.
No one said that.
What happens is that investment values are never audited.
Clients believe their Financial Statement and Online Screens.
Clients spend money like there's no tomorrow.
And why shouldn't clients spend money that the Exchanges tell them they have.
After all, aren't people paying all those Free Market companies Fees to ensure that the illusion is real?
I don't understand this.
Investment values can't be audited, because the values of stocks change by the minute.
I own stock in Walmart. In just 3 hours, stock values went from $73.2, to $72.5. They go up and down, up and down. Constantly change. Even when the stock market itself is closed, there are after-hours trading, and price go up and down constantly.
If you did a value audit, the results of that audit would be obsolete between the time where you clicked 'print', and the paper spit out of the printer.
So I'm not real sure what you mean by "no one audits the investment values".
As for clients spend money like no tomorrow. That's their problem. If the client wants to spend money until he's broke.... that is going to happen regardless of what the investment firm does.
There is no investment firm, that is going to magically invest your money, so brilliantly, that he can out earn, your stupidity as a person.
If you are determine to buy everything you want, regardless of if you have the money to cover it.... then it doesn't matter if the CEO of Goldman Sachs is your golfing partner or not. You are going to be broke.
Lastly, exchanges do not tell you that if you have, or don't have, any money. Exchanges can only tell you that based on the last trades, the assets you own have X value if you can sell them at the last value they sold for.
Let me put it another way. I have a grand marquis. I bought my grand marquis with only 60,000 miles on it, for only $3,000. Meanwhile another person who bought the same car, paid $6,000. How did I get my car for so cheap, while someone else had to pay twice a much?
Easy. I bought my car in 2008, when gas was hitting $4 a gallon. He bought his, in 2010, when gas was half that. When I bought my car, people were freaking out that the evil oil companies which supposedly controlled gas prices, were going to keep driving up the price until it was $8 a gallon.
So the value of a V8 massive luxury land yacht, was low. By 2010 when people saw the gas-Apocalypse wasn't coming, the values came back.
Everything changes in value over time. Everything does. Nothing in this world has 'intrinsic value'. Thus the stock exchange does not lie, or manipulate. They can only tell you want the value of your investment is, based on the last known trade.
But that doesn't mean the value will stay there. If another Enron happens, and they find out that X Corp was fabricating sales data, and you own stock in X Corp, the value of that stock is going to go down.
If the government institutes protectionism, and eliminates imports, and that kills domestic companies, the value of your stock will go down. No value is static.
