I always laugh at all the modern conveniences that show up in the "new world" - lumber cut with laser precision, plastic beach balls, gigantic panes of glass in the windows of the mansions every resident will have, etc.
None of which would be possible without the intricate, sophisticated, polluting, capitalistic infrastructure present in "this wicked world", not to mention the millions of people who would have to work the same types of boring, repetitive jobs to sustain that complex industrial-grade system.
You can't have all the plastic balls, beach umbrellas, leather shoes, metal belt buckles, etc. shown in their drawings for the billions of "resurrected ones", while simultaneously the only occupations in the world are [farmer], [construction worker], [Bible teacher] and nothing else.
Somehow those "new world speculations" always assume that technology and infrastructure will continue uninterrupted at 21st century USA-level standards.
