I've found that German-based companies are perfectly willing to pay 2x - 3x for an onsite freelancer than they would pay for an onsite employee, but they just don't do remote.
Since U.S.-based remote-only companies don't pay nearly as well as U.S.-based companies doing onsite - in my experience[!] -, this means that I could actually be earning more by doing onsite freelancing for German companies than doing remote for U.S. companies, but if you factor in the time & money for commuting and the increased cost of living from spending a lot of time in the cities where German companies offering interesting opportunities tend to be based, my disposable income/rate of savings, purchasing power, and quality of life are actually all better by doing remote.
