Life isn't fair and human beings aren't efficient... but the opportunity is there for those who strive for it and the bar to entry is set relatively low (by American standards of wealth; it would be much more difficult, if not impossible by wealth standards in a vast array of other countries). The "few" you're talking about are the majority (excluding dependents such as persons under the age of 18 and those living with family like elderly and disabled). The point in my previous post is that the monarchy comparison is a poor one... in monarchy, serfs could very rarely if ever move up the social strata... in America, it happens daily.
It's true, people should pay more attention to land ownership and realize there is a finite amount available... there is still plenty to go around but it WILL run out eventually. Owning land is a valid investment -- even above owning a piece of fine art -- as the ownership allows you to do things like drill for water, hunt, grow crops or raise livestock... you can eat the Mona Lisa but once and that won't sustain you much after that.
Rent and home prices are largely set by the housing market, which, I agree, is largely bullshit. But the market fluctuates up and down. Again, being smart with money and doing due diligence will yield a high degree of success in home/property ownership. That said, renting is only fit for the young who are transitory in their pursuits and only plan on staying static for a year or two. This gets back to my previous point but it's much smarter to by off YOUR mortgage by purchasing a home, rather than paying off someone else's by renting.
Being desperate for money is actually not what people are really desperate for... it's services and sustainment. Perhaps if schools taught more about agriculture, basic medicine, engineering and a trade instead of gender studies, people would be more capable of providing these basic necessities for themselves. Money, in any form, is just a fiat currency... it's merely a representation of approximate wealth. True power comes from knowledge and with it you can sustain yourself/others indefinitely regardless of how much monopoly money is in your pocket.
