If $1 million in cash means you can get a $4 million plot of land, spending 90% on T-bills means you have only $900k in bonds and a measly $400k farm (25% down). So you have 1/10th of the land and your bonds are yielding $22,500...

What really happens is as you pay off equity on your land and equipment, you leverage that into buying more land and more equipment.

Successful restaurateurs buy more restaurants, successful tech startups hire more devs and buy more servers, successful farmers buy more land.

Actual (successful) business activity yields more than investments, which is why they reinvest in themselves over stock markets.
