I'm not so sure about that: the younger generations are more concerned about the environment and about global warming - so I'd at minimum expect those portfolios to shift away from oil companies and ICE carmakers. If you want a green portfolio, Tesla is one of the top choices.
Note that this effect is measurable even between 65 to and 85 yo people:
Also note that in many wealthier families, tradition has the wealth skipping a generation. It seems after funding their own children's early years and education, it's more appealing to leave it to their even younger grandchildren as they leave the world. In many families, traditions die hard.
However, my point in posting the amount of wealth being inherited in 2020 wasn't to say a huge percentage of it will flow directly into TSLA, it was more of a general observation of just how much wealth there is at the top and that all this wealth is constantly looking for a productive home, especially in an era of low-interest rates. This has the effect of fuelling markets in general and making stocks more valuable. And as money flows to younger generations, a higher percentage of it will find it's home in companies like Tesla promoting sustainability.
During the tech boom of the 1990's, technology was fuelling a market boom due to the increased productivity that technology brought to many sectors of the economy. However, the great crash of 2000 led many to believe that technology wasn't the silver bullet for the markets.
Since around the turn of the century, information velocity has accelerated greatly. This is not to say it now travels faster than the speed of light (obviously) but it speaks to how the penetration of information flow and continuing adoption of data-driven processes in new applications have a synergistic effect on economic efficiency. The effects of this on economic efficiency should not be under-estimated. The economy can now produce more value at a lower cost than ever before. And the benefits are largely flowing to the top 3%. But here's the important part: We are still at the very early stages of the benefits that will be realized from these technological efficiencies.
Because the benefits are synergistic, and also because the benefits are still penetrating some previously untouched nooks and crannies of economic activity, the beneficial effects are only just beginning. Don't think of the benefits as one dimensional as you try to imagine specific examples of how technology can increase economic efficiency. It's not about the individual case studies but how they layer and combine to create entirely new ways of creating products and services and solving problems. Engineering and design become more efficient as well as the products they create. The need for many products and services goes away entirely. Products use fewer resources to create and build and more people can share the function of the same product. More for less. And a need for fewer goods and services to live better. Car and insurance salesman can be repurposed by the economy to provide better lives for more people. Maybe the masseuse that visits your home for 45 minutes twice a week was formerly a car salesman. Maybe, in time, the masseuse will be replaced by a smart robo-massage table able to sense exactly what your body needs. And the masseuse will be repurposed by the economy to provide other benefits to your life.
Some investors can only think in terms of an extraction economy. The rights to oil, rock, trees, coal or gold is resold at a profit after extraction and processing. We still need to do that but information and innovation are the new currency. We still need to extract materials and manufacture goods but we can do it with fewer people and at lower costs.
With raw materials and clean air and water in shorter supply, the economy is not contracting but expanding due to acceleration and availability of information and know-how. The net result is a boom of great investment opportunities such as the world has never seen. People who can only conceptualize the investment in something they think is tangible (like land or currency) will miss out. When you purchase land you are really purchasing the title to the land which is no more tangible than a share of a company. Both transfer ownership of a tangible asset to the purchaser. Even land ownership is fractional in nature. No one owns the entire county, state, nation or mother earth, they acquire a portion of it. And the value of that portion relies upon the proper functioning of the whole.
Money may be less volatile than stocks (on average) but it is far riskier because it is not a tangible asset, it is merely an economic accounting tool. Money is not productive in and of itself - only when it is used to purchase productive assets is it productive. True, it can be loaned out so others can put it to productive use but then you are only realizing a small portion of its actual return. It's much safer and more profitable to own actual businesses, with real production capacity, intellectual property and the ability to create desirable and useful things.
For all these reasons I think we are in the biggest multi-decade bull market the world has ever seen. And Yes, there will bumps along the way but, looking at the bigger picture, they are insignificant. People who don't see this bigger picture, the picture that shows how value is created over time, will not participate in investment returns but will be reduced to trading, and only catching small portions of the overall gains. They will think they were smart for cashing out with a $1,000 gain, a $10,000 gain or a $100,000 gain, not realizing they left more than 95% of the profits on the table with nothing to show for it but some cash (or whatever they bought with the money). This is how much of America (and the world) thinks. However, the wealthiest people in the world don't have a vault with all their cash (or even gold) safely inside, they buy other companies or portions of companies. That is true financial wealth, owning a portion of the economy.
