“What is your point? That we don’t need soldiers or workers? Are you really serious?”
Yes, of course I believe in 200 years or less we will need no soldiers and no workers, no one will have to sweat their bread, let alone to spill their blood. You don’t believe that? Actually, even our nonreligious and nonjewish fellow human beings believe that (you can e.g. google “singularity”). For the time being, and keeping in mind that only a negligible fraction of the current world riches derive from actual sweat in the field or in the workshop (which is what brought down economies such as ussr a couple of decades ago, while debt-based economies such as Japan are thriving), there are more than enough volunteers for both roles, whether among nonjews (properly paid for their effort) and among jewish people.
“Again, do you really think the country would be better off if every able bodied male just learned full time?”
Yes of course. You don’t? See above. If you have nostalgia of the days it was necessary to tend to cows and plough the fields, it means you never actually did it. Oh, in the evening, people were dead tired, yet they studied.
“Israel’s economy is amazingly vibrant.”
Fantastic! I congratulate you.
“How do you contribute to it?”
AHA! There you go. Why should I contribute to it? I do not have nor want an Israeli passport. So why should I contribute? Why am I supposed to consider the medinat “my homeland”? Why should I sweat it if it disappears, as other entities have done?
