There's a lot of talk about inflation and its causes. Is it corporate greed? Supply chain issues? One clear base cause of inflation less talked about is having an inflationary currency supply. Any other inflation caused by supply chain issues, corporate greed, lack of market competition, etc is just added on top of that. Fiat inflationary currency is a rather new invention in terms of the human timeline. In the US, Nixon is the start of it. Central banks aim for 2-3% inflation in "good years". The money supply expands, the portion of that supply a single dollar represents, and therefore its value, decreases. This isn't a conspiracy, it's government policy, and both parties gleefully support it because it benefits their rich donors.
Think of it: in the last 50 years, everything has gotten cheaper to produce thanks to increasing mechanization, outsourcing to cheap labor/low regulation countries, and extremely efficient supply chains. Yet so many things "cost more" than they did 50 years ago. Even basics like bread. What used to be 5c in the US in the 50s now costs $5.00. How is that the case? Shouldn't it cost less? Where is that "extra efficiency" going if not to lower prices? The answer: bread is the same value it's always been, the money has gotten less valuable. This is how they keep working class people running on a treadmill, never able to achieve economic mobility.
Inflationary currency devalues the currency you worked hard to earn by increasing the supply. It hits the middle class the worst because they have more of their net wealth in cash, often in the form of emergency funds, savings, and putting together enough money for a down payment on a home. Rich people have their money in assets which aren't harmed by currency inflation. Actually, even worse, it inflates the value of those assets! If the dollar loses value (all other things being equal), it takes more dollar to buy a share in Amazon, just like it takes more dollars to buy a loaf of bread. Poor people live hand to mouth, so their net wealth is not impacted much, but inflationary currency prevents them from saving and "moving up". If you want to identify the causes of increasing wealth disparity, the inability of people to save money and theft of value from the middle class via money supply expansion is a major one.
This works because people consider their own labor to have a fixed value. i.e.: they are willing to work a full week to just barely survive. They don't participate, or consider themselves to participate, in the ever-increasing value of their product, but just trade their daytime liberty for food and rent. Aggravated by propaganda like "you should be glad to have any job," and "you need to do whatever it takes to survive."
The counter to this is organization. Wages negotiated by leaders insulated from the threat of immediate eviction or starvation, who understand growing productivity, and can negotiate on an equal footing with the organized representatives of capital.
Agreed workers need to unionize but your first paragraph is preposterous.
No they don't. Do they not choose to apply to one place over the other? Scrutinize the benefits they offer, the location, the pay? Do they not make "lateral moves" to increase their wages? Do they not expect to make more as they gain more experience and knowledge? Do employers not generally pay "senior" employees more than new ones? Plenty of workers realize their labor does not have a fixed value.
The idea that only a special class of people can negotiate on their behalf is reductive and dis-empowering. Workers are capable of negotiating individually and as a union. And if my working conditions suck, and my union sucks at bargaining, I'll go find a job elsewhere or consider joining a different union.
