They didn't have the Rothschilds' banking system to bleed everyone dry back in those days. One could accumulate a fair amount of wealth and actually hold onto it, rather than having it all being taxed away. You didn't have some government controlling all the land to prevent anyone from living off from it--once you own land, you actually got to use it as you saw fit. It was possible to grow your own building supplies and use those, rather than depend on large corporations. Or, to grow your own food--which is why there was usually a surplus.
These days, however, everything is taxed. You own land, you have to pay taxes on it. Those taxes prevent you from holding onto wealth. You pay for transportation (gas, road user fees, license fees, and car taxes). You pay for food (growing it is by the big corporations only these days, not the small farmers). You pay for sick care (everyone goes to the doctor for their medical profile, regardless of need). You make money, you pay moon-high income taxes designed to prevent you from accumulating enough wealth to sustain yourself. Jesus didn't have to deal with gas prices, drivers licenses, vehicle registration, sick care insurance, and the like all the time as we do now.
