When engineering was more diverse, before round after round after round of 're-structuring,' work/life balance used to be decent.

In Engineering, if you are not part of the 'in crowd' (aka Indian), you will quickly notice the politics around you. There are issues with upward mobility and the projects you are given. If you refuse to work nights and weekends, you are seen as "not doing enough".

Also, by working with others, you can tell that many people got their jobs simply from being connected to another Indian.

Take a look at the hiring practices of H1B's. Stop hiring from overseas for lower wages to displace American workers. Why is the majority of the engineering org not diverse?

Stop the nepotism, but maybe it's too late. From the lower tiers all the way up, zero diversity.
