As long as the discussion is productive (and not me or you trying to "win the argument") then I like to think I handle criticism/debate/discussion well. I'm a writer and my goal is facilitate any form of dialogue good or bad. It'd be pretty bad if I can't handle new ideas or views of other people.
Getting to what you said, the theory of capitalism doesn't mention anything about jobs having to be meaningful or not, indeed. However, I believe that businesses are an extension of your being. How a business operates and what it focuses on is purely moved by someone at the top. With larger corporations it's controlled by a group. How jobs fit into all of this comes down to individualistic beliefs on how the company should be run or handle problems. If capitalism currently is all about giving consumers less options and extorting large groups of people, then jobs can be created maliciously to keep the status quo under the guise of creating another job.
I think to some extent that capitalism shifted along the way and that there needs to be some changes. I know from an investing standpoint the ESG movement is being encouraged by key investors and companies are following suit in being better about reporting and committing to changes (albeit at a pretty slow pace). But even something like that has government involvement to some degree in the form of regulations and requirements to provide ESG reports and measurements for emissions and such.
This I think is on the right track, where businesses can still profit but they are also providing for the people who are directly responsible for those profits. Even then, this movement would suggest businesses are moving away from capitalism and are embracing democratic socialism.
Thinking more about true capitalism, I think if businesses were to remain in a similar system we see today, certain aspects of it ought to be removed. I don't think it's natural that a handful of companies built up incredible power. We have government policies in place (or lack thereof) that allow companies to get away with all kinds of things. There was a point in modern history where billionaires didn't even exist and all of it was thanks to some government intervention and rules. That system got corroded over time due to rich people bribing people to run for positions of government and strategically remove and pick away at those safeguards.
A true capitalist system in my mind would result in someone starting a business and to keep running it without buying other companies or bribing officials. A free market would be dictated by the people who decide whether a company lives or dies. Today we have an illusion of that in that we can still boycott companies, but because those companies we don't agree with still have stakes or own parts of other corporations, they're still getting our money even when we disagree with how they do business. Instead if people wanted to accumulate power, they would have to build multiple businesses themselves or hire people to do that for them and even then it's not like they can buy out the competition in those sectors.
