Profit is another word for wealth, or value.
Profits are an essential part of a functioning economy as a they signal that a company is producing what people are willing to VOLUNTARILY pay for.
A company spends one million on raw materials. They turn those into products that sell collectively for 1.2 million.
That is a profit of .2 million, which is a signal FROM society are large TO the company that says, "We like what you make. We want what you make. We are WILLING to pay our money for what you make, at the price you are asking."
This is an ESSENTIAL signal that helps companies decide how (out of the many possible ways) to convert raw materials (or lower order wealth) into finished goods (higher order wealth).
Now, if a company spend that same mil and only got back .8 mill, that would be a LOSS (equally critical to a functioning economy).
It is a signal FROM society TO the company that says, "We like what you want, but we're not willing to pay what you're asking. Only a little bit less."
This "loss" signal is JUST as essential.
It's commonly thought, and argued, that with a smart enough government, they can DECIDE and CALCULATE exactly HOW to "best" not only distribute the wealth, but precisely WHAT higher order wealth to make from lower order wealth.
Every country that has tried this has FAILED MISERABLY and ended in lots of death and misery.
ESSENTIAL POINT
The ONLY WAY any corporation can grow large enough to FORCE PEOPLE to buy their goods at ARTIFICIALLY high prices is by enlisting the help of the government and it's always implied threat of violence against those who do not comply.
Without out the assistance of the governments, companies can only grow as large as people are willing to voluntarily buy their products.
Behind every HUGE CORPORATION that people wring their hands over, they are ONLY THAT BIG because they have politicians on a leash, or puppets on a string.
Unfortunately, people's cognitive dissonance makes many REFUSE to believe this.
Because getting a job is hard.
Switching jobs is hard.
Running a company (no matter how big or small) is extremely difficult, as you must always watch out for your competition, trends, continue to be innovative, etc.
People would MUCH RATHER believe the simple and binary idea that
governments = good and
big corporations = bad as those beliefs allow them to believe they CAN get more OUT of the system than they put in.
AND it gives them plenty of ready arguments to signal their own "moral authority"
(e.g. those that oppose my ideas MUST be white, redneck, republicans).
