Claiming that even a majority or plurality of economists overall agree with Piketty, who advocates for some wildly unpopular economic policies and is a literal socialist, is absurd, so your group of "independent economists" must be pretty homogeneous and small.
When even Adam Smith supports the regulation of capital, this can be considered a fairly mainstream position.
I can point to dozens upon dozens of independent economists (by your definition) that disagree with the use of confiscatory income tax rates and wealth taxes, so I don't know what your argument is here.
The pros of software are so OP that it hard to justify investing in anything else. Software has incredibly low cap-ex and incredibly high margins. Five humans with five laptops can create a lawn maintenance app worth tens of millions.
To get that same value from, say, building lawn mowers, you need a factory...annnd already the value prop is "nope".
Take note that there is no hardware version of Hackernews. There is no hardware/manufacturing VC scene. Hell even the hardware that is produced today is just a vessel to sell a $19.99/mo software subscription to use the product. Look at what Tesla did, they are getting a reality check on their cars, but Ah!, Tesla is now a software company developing a software package that turns hardware (their cars) into reoccurring profit machines!
Software has eaten the first world, and this is what is looks like. A hyper inflated tech scene where all innovation is happening, and a totally anemic everything-else scene (except finance, that's huge too).
And

A lot of the 'growth' we've seen seems to be consolidation and bilking of the consumer by rents. If we look at other countries with actual competition in manufacturing like China we see tons of brands with quality everywhere from use once and throw away to actually really good products. The profit chasing will eventually kill us as we have nothing that will produce actual value.
(Also I love how you're getting voted down for pointing out the obvious).
The problem is, once the gold standard fell and the rise of fiat money began, the financial markets became self-serving, with hordes of middlemen extracting the tiniest amounts of profits along the path, speculative trading driving up food prices, and people's care in old age no longer backed by the government in the form of a "societal contract" but by, essentially, betting on the economy ever growing and growing.
The gamble went on decent for a few decades, partially powered by ruthless exploitation of natural resources, but in the end the fundamental and long ignored issue of infinite growth being impossible (as anyone who ever played Paperclip should know) is now coming home to roost. The domestic resources of many countries are effectively exhausted (coal, gas and oil in Western Europe), leading to unhealthy dependencies on those countries that still do have these resources, and the consumer markets are either already saturated with cheap foreign-made goods or simply don't have enough money any more because rents are extracting too much money out of the people.
