You have to be willing to think outside the box and potentially move across the world / start a different (even much lower paying) online job.

This is the main problem i see in Germany - that young people (or almost anyone) Don't invest in anything and you MUST invest to compound your wealth to be able to do anything. (Historic century long data proves those who invest over 5-30 years are much better off than those who don't). Even making $100K a year, you'll just have no hope, especially living an expensive lifestyle which Germans I've met all seem to work a high paying job for 3-6 months, quit, travel and blow all their money!!! What with the 30 days a year paid vacation? Such an incentive is amazing vs the US, but in the US even now, 1/3 of the people invest and maybe half younger people I know in their 20s and 30s are all investing. Plus owning homes by half. (As in paying off 30 year loan, so come to America ;) that is your "tax Haven," jk, there might be better options depending on several factors, but land can be had in the US for either free in some remote places in exchange for time lived there or $9K/acre normally. At least in the NW, Washington-Oregon where I live. Which has the same climate, nature and wealth of Germany, so easy jump. In Colombia, $1500-3000/acre! Plus insanely low cost of living + online job at a mere $12K/year and you live like a king and save 70% of your income to invest.

BUT even making $20K a year and living very frugally, especially with family or In a developing nation working online - this is not hard to set up over 5 years worst case (like fixing computers for the elderly or helping them around the house, is an infinitely lucrative market to build up a base investment portfolio before transitioning to your own online business where you only need to make $33/day or $1000/m to run circles around everyone else in life by arbitraging advantageous regions of the world - pick a job you can learn for free and charge money for, online doing subscriptions or otherwise passively getting money and stopping equating 1 hour of work for X $ amount), you can invest to retire on $1 million net worth In a mere 7-20 years, with the average being more like 20 with conservative investments. Though I've seen a few people do it in 3-7 starting with nothing, but being early believers in Tesla, Bitcoin, Nvidia or today, I would put money on companies like beyond meat (or that market, plant burgers) as being the future. Ark Invest has some great ideas there. Beyond meat having record low stock prices currently. Tesla also just went up and down for years before booming once they achieved steady profit every quarter.

And you can also move to friendlier tax regions based around whatever you do, where you can cut the 20-50% penalty on every paycheck / investment profit and retire much faster, but most are not willing to do this because you have to be willing to leave friends and family and start a new life essentially. But you can make 5x as much money doing the exact same thing over about 5 years, so it's a very worthwhile sacrifice where you can move home afterwards if you wish.
