I'll give it a shot.

They've been holding back LOTS of great technology. For example, you can have an electric car, but without (at least most) of the battery. Recharges off either the earths magnetic field, and/or ground plane wireless energy transfer that Tesla had developed decades ago. Never need to fill up your car or do oil changes; faster, cleaner electric.

Same with electric to your house. See previous.

Get rid of IRS. They and many other 3 letter agencies were brought about as a result of something the Deep State hacks came up with after causing the problems to begin with.

When you don't have to spend your life working just for the government taxations and vehicle fuel, how much more do you have? Friggin lots. You've just paid off your house and have broken out of debt slavery.

Food? Again, technologies and previous ways have been held back/"disappeared". Pyramids weren't just for burials. They apparently have a way of making food grow much larger without all the chemical and biological onslaught. And can be made from wood/copper/plexiglass to do so. They literally buried a known pyramid in Bosnia area, both with dirt and on internet searches. http://www.semirosmanagic.com/en/documentary.html

By the way, anti-gravity materials were discovered (LK-99). Back in 2011 or earlier. https://www.altpropulsion.com/events/

And all that pales when you start to realize we had a great world God made way back when. And a better understanding of Him is in the near future. Exciting times indeedy.
