As much as I nodded along with your exasperation at the parent poster's (father's) demonstration of bias, you can't compare long-distance public transportation infrastructure in places with the population densities and growth rates of Germany and California, two extremes in that sense. California has 1/5 more area, with half the population, and that population has almost doubled over the last 35 years, versus a few % growth in Germany.

You very much can. Parent didn't ask Californians to build infrastructure in Yosemite or the Death Valley. Heck, not even in Bakersfield.

How's that L.A, San Diego, and San Francisco public transportation infrastructure? Places that, if anything, have more population density than the most populus German cities?

The US mostly relies on air travel, and it's not too inconvenient if you can avoid major hubs like SFO and LAX. The population of those metropolitan areas isn't the problem; it's the distance, as well as the lower demand for travel between them. California is also more seismically active. You can build a passenger HSR system in California, but the cost/benefit is going to be worse than somewhere like Germany.

Distance wouldn't be much of a problem. It isn't much longer than Paris - Frankfurt. Chinese trains cover the distance in 2 hours. It would work from a European perspective, but Europe built most of its networks decades ago. The Chinese aren't just building train lines, they are building entire regions.

Everyone complains how few things can be built in SF or LA, but suddenly having a lot of space available is something negative? Californians have a dream scenario on their hands as the high cost of construction can relatively soon be offset by the huge gains in capturing the global tech market. Something that will pay off for a century. And they should have the money to do it. It is probably one of the best infrastructure investments available anywhere.

Wendover Productions made an interesting video on the economics of Trains in the States:

The point is, it's still very difficult to do basic things in California: get to work and have a place to live. This is progressive?
