I am really considering teaching my wife how to code just so she can understand my rants better

I feel like the gravity of my ranting is not communicated well enough without programming context

So I'm about to get a job offer

For some context, I live in a low tax country and my gross salary is 56k (incl bonus). I take home about 3600 per month. And there's a 10% bonus
Next month I have a raise to 61k and will take home 4000.

I just finished a few interviews with a very interesting company in another country and the recruiter says they are offering max 66k.

Problem is, it's in a high tax country (Sweden) . So that 66k means take home pay of 3600... That's a 9% pay cut over what I will make starting next month.

Now I'm not sure how to approach this. I calculated what I want (10-15% raise over my current - next month's - salary and the number is *way* higher: 90k.. This means take home 4600 (15% increase)
I also calculated what it would take to match my employer and even that is much higher at 77k.

The recruiter asked me what they would need to offer me for me to accept and says max budget is 66k. This is of course after I told him 66k would net me less than I make now...

There's also the possibility of working remotely (as a contractor I am guessing) from where I am, and I think in that case the 66k would net me roughly the same as my employer, but I'm not sure as there might be additional costs.
But being a contractor means the employer doesn't pay any tax contributions for me, right? I calculated they would be paying 22k tax (on top of 66k salary) which as I understand is freed up. If that's the case maybe I should be asking for more (as contractor)?

How do I approach this? Anyone been in a similar situation?

Every Monday I am privileged to wake up 1. 5 hours earlier and listen to executives talk about what meetings they had with potential customers and what news about ongoing agreements with other potential customers (which have been in the pipeline for 1 year or more sometimes)

Why is this necessary?? There has been virtually no progress on any of the topics discussed. At least nothing that concerns us devs.

Instead we get to wake up earlier, waste 1 hour, and get bored listening to what essentially seems like a sales speech while convince the employees the company is not spinning its tires while stuck in the mud.

How do you deal with a manager like this?

My manager is close with 2 colleagues who constantly suck up to them and who they're pretty much friends with.

I don't particularly like to do stuff like that and don't really like the manager either (in my opinion they're incompetent) but now, often when I write code, the manager will have those colleagues "check" it. Not peer review, as I never get feedback. Just occasionally I'll find out they "checked" my code to see if I work/do my job right.

This is despite me being more senior than the both of them, having contributed far more actual code to the project than both combined and one of them can not even write proper code!!!

I'm honestly tired of sitting here and working on boring long tasks, and then being treated (behind my back) as if I am not working.

It's building up this paranoia in my head that this problem is also making other colleages/my boss think that I am slacking.

I used to be so close with everyone at the company, but now I feel completely alone and alienated...
