We're talking about one company here. These employees were not slighted in the least.
Company A, B, and C - Position 1 makes 35-45k per year. Position 2 makes 75-85k per year.
Company D - Position 1 makes 70k per year. Position 2 makes 75-85k per year.
Why should the people in position 2 at Company D be disgruntled in any way? They are already being paid what they are worth and would be similarly compensated if they quit and moved to another company.
They should be proud of what this company is doing.
Someone said this at another forum:
"There are two kinds of people in this world: People who value their worth by their own merits, and people who value their worth by how many people are beneath them."
If the latter describes you perhaps you should rethink things just a little bit.
