If so many office jobs are easy to do and can be easily automated, why don’t capitalists and CEO’s jump on this and maximize profits while minimizing employment?

This recent viral post talked about how office work that can be done in a few hours or weeks are scheduled to be completed in weeks or months.

In addition to this, if workers got their work done faster or got it done before deadlines, they'd actually be punished by their temp agencies or bosses.

And this baffles me.

If capitalists are so insistent on cutting any corners possible to maximize profits while minimizing any costs, then why aren't they allowing their office culture to become more streamline to minimize the number of employees necessary to perform relatively easy jobs?

The only thing I can think of is;

Real Estate.

It's essentially the same reason why businesses and politicians are so insistent on everyone coming back into the office despite how easily the job can be done from home and how remote work cuts down on unnecessary costs and time for employers and employees.

It's why McDonald's primary revenue is from the real estate and property their franchises own and not their burgers.

It's the only way the costs of employing so many people despite how the work can be done so easily in such less time can actually lead to profits for these businesses;

The accruing assets of their properties and the land they're on continues to grow every single year, and that real estate is used in bonds that they and Wall Street invest in to grow their own portfolios.

But are there any other reasons for this? What are your thoughts?
