This is precisely why when I started my company I committed to only hiring contract devs for 10-20 hours per week. No meetings. No bullshit. I pay you a high hourly wage, you do as much (often more) work than if you were a salaried 40 hour FTE, and you likely make more money in the process.
The model of work and the 40 hour work week is so fundamentally broken I feel like I'm in a perpetual twilight zone state when I talk to people. They think it's normal and okay to have 3+ hours of meetings per day and barely get any work done. I will never understand it.
My first 7 years of work life outside of college consisted of THOUSANDS of pointless meetings and months of pretending to be busy. I've promised myself I will never do that shit again, and I will not let my business succumb to that style of work.
