I have very little scientific learning or training. Why can't we manufacture helium if we need it so bad ?

I don't believe that there are that many chemical reactions that could do the job (essentially because a chemical reaction would have to rely on compounds that already contain helium, and these don't exist, certainly not in natural conditions). So that leaves radioactive processes, either fusion or fission. Fusion is energy-intensive, fission less so, but in both cases you need large quantities of the starting product to get much usable helium. In either case, it's more practical to rely on natural resources.
I think usable helium might be a by-product of fusion power stations, but since we don't have any of those yet either...

The only way to 'Manufacture' Helium (which is an Element not a compound remember) would be to create on Earth the conditions which exist in the core of stars , such as the Sun. In a star Hydrogen is fused to form Helium which gives the heat and light, the pressures and temperatures needed are beyond the comprehension of most people. This is what Nuclear Fusion research is about, IF we ever manage to do it , all our energy problems will be solved for all eternity. Limitless power for ever!!
Just to add the Helium we do have on Earth is so light that once released it floats upwards and ends up being lost into space from the top of the atmosphere.

Note the details in the link. The find could be as much as 54,000,000 Cu ft which will supply our needs for 'Several Years' . Here on Earth we are still very short of the 2nd most abundant Element in the universe! This will last 10 years at most.
Without Helium MRI scanners will not work, can we afford to waste it on 'Party Balloons'?

Yes, high purity helium is extremely expensive and the price is increasing annually. My laboratories use piped high purity helium for both GC and other applications and we get annual reports from the faculty bean-counters pointing out the high cost. To date, they've not restricted us but it's something we need to keep in mind.
To some extent, we're fortunate as we send researchers with likely high usage requirements to the university science park research laboratories and they pick up the bill!
Some government research laboratories use a good amount of high purity helium daily and I've been known to run the odd GC analysis in such places myself.

So many people did the same degree as I did that all the job vacancies I could find were specifying 5 years' experience in GC or some other hurdle which meant I couldn't get in.
A couple of years later, they played switcheroo and started insisting on "recent graduate", as if knowledge goes stale or something.
Not that I'm bitter, or anything…
