As a Colombian I can say that most people declare full income due to fear of being chased by DIAN (colombian IRS) which is probable the most corrupt institution in the country, meaning that if you don't declare your full income they'll shake you down for everything you have, I've personally heard cases of people making innocent mistakes in taxes and getting extorted for millions upon millions by "honest DIAN officers".
The strata system was created to create a form of "equality" where rich people helped poor people via subsidies, however, this has been abused by both sides since the very beginning (poor people using 10 or 20x the normal amounts of water and electricity to "fuck the rich people" and rich people paying to get their houses declared "historical patrimony" to avoid paying subsidies)
In the end, the strata system was created for a different society that we have right now, nowadays almost all buildings are estrato 3 or 4 in areas where estrato 2 was the highest possible.
I have no idea what could replace the strata system (I'm not a political scientist or anything that resembles that) but I do agree that the system is broken and should be replaced by something better.
It's mostly a US (not American, America is a continent after all) thing.
In Latin America getting laid off means being called to HR in the morning around 10:00am and getting told "you're being let go, please clean out your desk, fill in your boss on any pending work and finish your workday"
I've only seen one person escorted out of the building in the US way and that was because he was stealing corporate info.
"on mobile" these days can be anything from a 3'' device with 512MB RAM to the device you mention.
It's very easy to assume that everyone has the latest device in an affluent society that doesn't have much of a problem buying the latest and greatest, but I can assure you this isn't the case in most of the world.
You're failing to see that Google is used everywhere in the world and not all countries (in fact, very few) have markets where the standard device is what you describe or where everyone has blazing fast LTE available everywhere.
For example, there are places here in Colombia where 2G is the norm, that's the kind of people AMP is helping, not the bay area kid that has the latest iPhone and 100Mb Wi-Fi
I've been a product manager for about 2 years, coming from a development background, I suggest getting as much technical background as possible and a nice helping of people skills.
It's been said before but the PM is mainly a servant and facilitator, and it helps a lot if you know what you're talking about (we have a PM here that confuses VPNs with DNS, doesn't know how to report bugs, etc.)
IMHO, getting to be a PM is mostly demonstrating that you're dependable in a lower level position and showing that you have enough knowledge/leadership skills to get the job done.
