Govt prints money, money is worth less, assets go up in value relative to fiat currency over time, regardless of actual market share growth if the asset is a business.

If I charge $1 this year for lemonade, but next year I charge $1.10 and the same people still buy the same amount of lemonade, my business is now worth 10% a year later, without gaining new customers.

With quantitative easing as the main strategy of the Fed, we'll not see an end to financial market highs. Short term corrections in industries, sure, investors want to take profit and reallocate and provide returns.

If you are not invested in assets, as the value of fiat currency decreases due to inflation, you become poorer as a result.

Financial education is so lacking among the poor. Even if they had the money to invest, they wouldn't because they don't understand the system, and would rather save up some cash which devalues over time.

Illiteracy of the financial system and its inner workings is one of the main reasons people are not able to generate wealth and put their savings to use. Hell, a lot of people I know don't even take advantage of 401ks, because why invest in something where they think "I can't access the money til 30-40 years later" what's the point.
