I have to agree with you. A huge number of regular (albeit comfortable) people, also pay > 50% in income tax. When they complain about "the 1%", it's because they see people like you having the means to get out of this system. They're angry you're not suffering alongside them.
My goal with this move is to leave for 5 years or so and acquire enough wealth that I will be personally comfortable for the rest of my life.
At which point I would likely to move to wherever I preferred to live in the world (regardless of tax rate), and to work on something more enjoyable and meaningful rather than simply chasing dollars.
I started a couple of small niche SaaS tools over the years from age 18-23) which helped me amass low 6 figures. I then jumped head first into the affiliate marketing space for a few more years which took me to around $1M net worth.
From there, I just leveraged my money to launch a couple of other businesses in gaps I saw in the market, primarily in the ecommerce space. Now I have a few businesses that I continue to run on a daily basis.
It's very tiring if I'm honest, I'm an exceptionally hard worker which has definitely attributed to my success, however I have an extremely hard time delegating which means I still work around 15 hours average per day (and have zero staff). It's something I'm working on.
I've also hit the low six-figures from crypto, now looking to diversify into real estate (a friend is rapidly becoming wealthy and retiring early with low fixed rate mortgages in Germany and is luckily educating me) and building an affiliate site (just dipping my toes in outsourcing and YouTube soon, no way I can grind out content forever). If you'd ever like to shoot the breeze let me know. Email in my profile. I'd love to get in touch.
I tend to doubt OP is suffering at $450k/month profit, even if half of it goes to tax.
It's almost like there's an entire society outside the business to think of.
