A couple of comments as a European who lives and works in the US:

- I'm surprised that you find salaries lower in the US than in Europe. That said, if you compared freelance/consulting rates to salaries, that's Apples and Oranges. If you compare salaried positions, even on the East Coast, the salaries should be noticeably higher than in Germany. The extremely high compensation that people in some posts are talking about are generally found in a few, extremely high cost of living areas on the West Coast.

- I would expect AWS focused cloud migration consulting to be in demand in the US more or less the same way it is in Europe. That said, you'll be in competition with the usual consulting/outsourcing suspects and with no network, that might be a bit of an issue.

- The big financial hit for freelancers over here tends to be health insurance, and that's going to be rather expensive at your age (I'm a few years older than you). If your wife's job does offer health insurance for both of you, that's a major bonus. In fact that's pretty much what keeps me from freelancing with 30+ years experience (I used to freelance in Europe).

- Yes, there are differences in the quality of life over here. Not all of it is applicable to freelancers for whom paid vacation time isn't a thing, but it's a different mentality when it comes to work here for a lot of people.

To put not too fine a point to it, yes, your age can be an issue. Despite age discrimination being illegal, it's still rampant in this industry. OTOH I don't have that many problems finding work, and I work with a few people who are older than me and also don't have those issues. A lot of it depends on the company you're working for or with - some of them are looking for cheap young cannon fodder, others are willing to pay for experience and deal with grumpy old people :).

The other question you need to answer for yourself is the motivation for moving over here, even temporarily. If you're looking to make untold riches quickly, it's probably not that great an idea. While you should be able to at least match your German income over here, it might take a few years to get back to that level.
