You need to get out more and meet people who own and run businesses. Not only do businesses vary greatly in size, scope and the way they treat customers and staff, but the people who run them are all very different too. they each have their own motivations for doing what they do. What do you do for a living?
I'll say I painted with too broad a brush there. Replace it with "people who control the largest companies" if you prefer. Examples of what I'm talking about more specifically:
-all the world's largest financial institutions are criminal organizations engaged in, at minimum, moneylaundering and fraud
-a very large proportion of the financial services industry provides financial services to people who make their money by criminal or unethical means
-any company involved in global supply chains is almost certainly involved in some criminal behavior. Responsibility for this is I would put mainly on the largest and most powerful actors involved in any given value chain. An example would be Apple using its market share to demand phone parts from Chinese suppliers at prices that ensure the suppliers are committing fraud, violating labor standards, or both
-all sorts of fraud, labor standards violations, unfair labor practices, and so on are
endemic in the United States.
Every crappy low-wage job I've worked in my life, with one exception, was for an employer who violated labor laws.
This list is not exhaustive, obviously, but I think we really underestimate the degree to which economic inequality today, at the country and at the global scale, is driven by behavior that is criminal even according to the flawed legal systems we currently have. As for what I do for a living, it's strategic research for a US labor union - so my job involves precisely learning about the bad behavior that employers in our labor market get up to. I'll be the first to admit that this has prejudiced me to some degree, but my work has also driven home how ubiquitously criminal the ruling class really is.
