Aren't most retired people's money locked up in gov pension and social programs as opposed to the USA where you're expected to mostly self-fund retirement with 401k, IRA, and savings?

So older US people have more control of their retirement funds than Europeans?

I don't know how this related to robocall, but I like the question!

I can only answer for Denmark, but there we have a thing called "ratepension" which I think is similar to a 401k. Retirement age in Denmark is 73 and the public pensions do only cover the bare minimums – you also need at private pension.

In the US, the robocalls typically target seniors that aren't able to identify the scam.

In the US, we have 3 "pillars" of retirement income that we are told to keep roughly the same size: Gov plans (Social Security), personal savings, employer sponsor plans (401k).

I had always assumed in Europe, most people expected the gov to fund most of their retirement (70%?). Whereas the expectation in the US is social security only covers ~33% (although for many people its 100%).

At least for Denmark, the expectation are more or less the same as for the US.

I don’t see how that’s the only dimension to look at when identifying addressable markets. Actually I don’t even see how it’s any dimension at all since you just can’t target “Europe” as a whole with a single solution that doesn’t have dozens of bespoke per-country exceptions. France is just about as different from Germany as any North American country.

EU has harmonised the mobile network market meaning that you can basically call cross borders as if it was a single market.

Anyhow, I don't know of any single country in the EU that has issues with robocalls.

I get spam in WhatsApp and Telegram sometimes. Easy to block and report though.

I think the inscrutable European languages helps to protect us from scammers.

Who speak different languages. It also costs much more per minute to call EU cellphones.
