Edit: This question attracted way more interest than I hoped for! I will need some time to go through the comments in the next days, thanks for your efforts everyone. One thing I could grasp from the answers already - it seems to be complicated. There is no one fits all answer.
Under capitalism, it seems companies always need to grow bigger. Why can’t they just say, okay, we have 100 employees and produce a nice product for a specific market and that’s fine?
Or is this only a US megacorp thing where they need to grow to satisfy their shareholders?
Let’s ignore that most of the times the small companies get bought by the large ones.
It’s all based around fractional reserve lending and interest. Banks take in deposits and lend several times the deposit amount at interest against that reserve. To pay back the bank the business sector has to grow in order to pay interest on the principal. Make sense?
no. You can pay interest out of your profits without growing. And many businesses don’t have significant loans.
