I'll bite ...

crushing the productivity of these workers

What "crushing" of productivity are you delusionally on about?

I can find any number of sources showing that productivity has been on the rise for decades, and has continued to rise as Millenials and younger entered the job market. There is no "crushing the productivity".

The rise of the internet and social media has led to a culture of instant gratification ... This sense of entitlement

Millenials and younger have gone through their entire school life being told "you need to do well this year at school, to get into the top set next year, to get into a good university to get a good job". We/they have been told this by every generation above them, for their entire lives. The have followed this, listened to their elders, worked hard through school, sat meaningless exams, gotten good meaningless grades, they have gone to university. They have worked hard their entire lives ...

Just to be told, "culture of instant gratification" "you're entitled" "you've not done the grunt work". It's selfish of the previous generations to not recognise this.

Your entire comment rings as "needs evidence" to me. To the point I'm not sure if it's satire or not. You've failed to put in any grunt work, evidence anything or source it as anything more than conjecture.

They expect to be rewarded simply for showing up, rather than for producing quality work.

This is the opposite of how I see the world, as it stands. Look at the people calling for maintaining or increasing working hours. Look at the people calling to work in office. It's the previous generations expecting people to turn up, in office and sit there for hours so they can be paid. They are expecting people to be rewarded simply for showing up.

Look at the people calling for unlimited holiday and reduced workhours, where failure to deliver is a disciplinary issue. Look at the people calling to work from home, and have the quality of their work assessed, not their dress sense or punctuality. Look at the people driving quick delivery, rapid review and peer appraisal of work. These are the people who are focussed on delivering quality, and not getting paid simply for showing up.
