The post you referred to was in response to a claim that base pay went up 100% since 2001.
You said few remain E-1s. The Corps has a bunch of E-1s in the fleet, some of them are E-1 the second time.
I saw one E-1 in the Wing in 21 years, had him as a duty clerk when I had the Group duty. He claimed it was his natural rank, not a retread one. I think he was a FAP from the Marine Wing Support Squadron (MWSS).
The fact is that base pay hasn't gone up 100% since 2001. And those who are claiming 'civilian equivalent' pay count as pay BAH/BAS which no private I ever heard of got. If he was married he got quarters pay for the old lady and maybe comrats, but I doubt it in the Corps. If they wanted you to have a wife, they would have issued you one. Plus all privates had to maintain a barracks room at any rate.
As a 2Lt I would have loved 42K but as I was single living in the Q for the first 7 months, I got base pay and BAS. Out of that came 2.5k for uniforms.
Confusing.
An E-4 over 3 yrs in 1996 had a monthly base pay of $1209.30. So the increase between 1996 and 2001 was roughly $291. The increase between 1996 and 2014 for an E-4 over with 3 years is a $984 increase in the pay for E-4 with over 3 years. Actual base pay only increased $984 over 18 years.
