If you get laid off in most western countries you get ~10k over 6 months in unemployment benefits from the government + accrued vacation time and possibly more. Assuming you where ok financially before you started that's a long time to look for the next job especially if your cut down your lifestyle.
PS: It's often the case where people get a little warning and end up finding a job before they get laid off. From the companies perspective the trade off is a little more chaos up front for significant savings on unemployment insurance.
It's true about the US, and if you go on unemployment the company that let you go can be on the hook to pay for about half of it. So you definitely want your ex employees to get another job fast.
Every time I've went on unemployment, it was waaaay less than 10k - if I managed to get 1000 bucks a month it was a miracle. Last time I did it (years ago) I let the money sit in the bank at Chase because I had lost track of the debit card they (unemployment) sent me. Until at a certain point they had to close out the account. This was years later, and I had (mostly) forgotten all about it. I had to go down to the bank and prove who I was to withdraw it.
So - why did I let it sit? Didn't I need it? Well - no, not really. I applied because I could; I was laid off my previous job, so I thought "hey, why not, I earned it, right?". So I applied. Kept my notes and log and such. But before I got the confirmation and debit card, I had a new job. Before that, I just used my savings (actually, I don't even think I had to dip into that - I had more than enough to cover things in my checking, after the severance pay).
When I finally did withdraw the money, it was something like $400 or so for a couple of weeks.
You do need to pay taxes on the income, and I assume dev's are at the high end of the scale. "The current weekly benefit amount provided by the Maryland Unemployment Insurance Law ranges from a minimum of $50.00 to a maximum of $430.00." https://www.dllr.state.md.us/employment/claimfaq.shtml
The high is 430 * 52 / 2 = 11,180 and the low is 430 * 52 / 2 = 1,300. But, again before taxes.
