I seem to recall reading somewhere that genes selected for among European survivors of the Black Death improved resistance to HIV.
But I would be totally down to watch a series about economic development during the blip (and after the blip!). If half of all people disappeared, you would probably see a massive surge in wages. But it might not be enough to keep society alive. Assuming they did solve for it, the post blip period would almost certainly result in massive global crises as countries which experienced heavy immigration are now overpopulated and countries which experienced mass emigration now have a lot of people with basically no societal infrastructure anymore.

We aren't living in an agricultural-trade system anymore.
Besides, we need fresh bodies to populate heavenly colonies.
despite not living in an agricultural-trade system nothing has changed. if the economy is growing but the population is shrinking than either the working class should have more money or the rich and their corporations should. you should be able to get the same amount of tax out of either than you lost through the shrinking population. the rich and the corporations have shifted the tax burden to the growing population which helps them make more money in multiple ways... by paying less to workers because of more competition and then passing on the entire tax burden to the wage earners.
we have no heavenly colonies and when we do they will support very very small populations, say at most a million people probably 10,000 years in the future... in the meantime we'd be lucky to get 100 people to create a self-sustaining colony.
