And what does that "fact" have to do with manned space flight? We didn't actually stop doing anything of those things just because we have machines to help us. In particular, did you stop traveling just because that is in the "grip" of machines?

And you should lump the development cost in there too. Low marginal cost claims are an often effective political gimmick for glossing over the high front end costs of development. But you can only take advantage of those low marginal costs, if you actually make the plane in volume. Both of those jets failed to meet the promised volume numbers.

The gold dollar was about to put a check on Lyndon Johnson's 'Great Society' crapola, but Nixon defaulted on the gold dollar, crossed the words 'I owe you' from 'I owe you X dollars' from the bank notes and called the little paper previously known as the 'Federal reserve note' into 'dollars'. This is what allowed the government to perpetuate its growth to the gargantuan size it is today and it is what killed USA economy reversing the economic growth in USA and eventually wiping out the economy completely.

As to statistics, some people compile this data, of-course unemployment rate shows some of this but the details of unemployment are much more important than the compiled averages, the poorer segment of society, the black Americans have suffered higher unemployment rate since the programs against poverty started, than ever before. Actually before the minimum wage was introduced in the 1938, unemployment among blacks youth (16-25, formative work years) was lower than among whites by 15%. Actually each 10% increase in minimum wage mandate had a disproportionate decrease in employment upon the minorities, which is counterproductive if the goal is to decrease poverty, of-course it was not, the goal was to turn people into dependants, voting for bigger and bigger government, while growing the said government.

The gold dollar was not allowing the government to carry with that goal and Nixon chose to default on the actual dollar than to abandon big government ideology.

You can drive from Baltimore to DC and back without noticing that you have a flat tire?

Actually I have done precisely that, but it was a rear tire on a front-wheel drive. Only noticed a problem when listening to AM radio and hearing a "click-click-click" when going at low speeds. That was the nail in my tire hitting the road and shorting out the static building up from the tire rubbing.

As an experiment, it is close to pointless. As a technology demonstration it has somewhat more value, though perhaps not enough to justify its inclusion. You could do this a hundred times in those basements and it would still not be done on Mars. For a technology to be demonstrated in a particular unusual situation or environment, then it sooner or later has to be deployed in that situation or environment.
