Why it is hard to start a small business

This pretty much sums it up.

Hotel built in 6 days

Only in China. Of coarse. I am thinking of all the limitations that would prohibit this same feat from occurring in the US. Labor cost would be a major one, as well as the ability to work 24 hours a day. Or meeting all the various construction codes, this would be especially important in terms of what you could and couldn't construct something with. You can't even get an LA building inspector out to the job site in less than 3 days for a preliminary inspection, and then it would be 3 more for a final inspection. Even a single story large concrete box takes 6-8 months out here.

One step I felt was missing, I didn't see them lay the foundation, just drying the concrete would take a day at least.

This is a pretty fun presentation, I liked the peak break-up times.
