Most of you probably know the memes about homes not being affordable to younger generations. It is true, that they are, at least, less affordable as illustrated by Figure 4-1. The reasons for that however aren't evil Landlords, who want to leech as much as possible. It is more a combination of several factors:
Years of Bad Politics™️ has led to too few houses being built and now there is a shortage. As any highschooler, after paying attention in economics for 30min, can tell you: low supply + high demand = bad for consumers
Following that, most young people want to live in big cities, preferably the few biggest ones. That puts additional strain on these local markets.
Another big contributor to this problem is that Homeowners want to keep the value of their homes up. Anyone wants their assets to rise in value. But since they are the ones who vote in local elections, they vote to keep houses expensive. That means weird zoning, no new Homes etc.
In defense of renting
Renting apartments or even Houses is a good concept. I pay some entity to keep my housing repaired, up to code etc. As a consequence I don't risk most of my net-worth being deleted by a storm or similar. Renting is more expensive than owning on average, but renters have none of the risk that owning implies.
I personally like fixing and modifying stuff. That includes Computers furniture and Houses. However I also know a lot of people who don't. They don't trust themselves to drill a hole in a wall. For those people shifting the responsibility of fixing smaller things to a landlord can be beneficial.
It also frees people up to move around, when their job/life requires it.
Solutions
Build more houses.
Its that simple. Cities need to rezone and remove houses in favor of multi-family buildings or even skyscrapers. Houses in a city make no sense. You want to be in a city to have a lot of people in a small area. Why would you spread out everyone in suburban wastelands.
If you want a house yourself, go to rural areas. I know you nerds are spending your entire social life on the Internet. It's probably way cheaper to get a fiber connection into the middle of nowhere than paying for city houses. "Mimimi, but there are no queer communities" Then start one. Imagine how powerful all you queer furries will be if you take your tech jobs remote and save like 70% of your housing expenses. Just don't spend the extra cash on more porn.
I know that when I'm done with my degrees I'll be building my lair where no ethics boards will find me. My machines will be efficient and my fungi growing fast.
If I have convinced you to embrace the hermit life, come join me. I am always in need of more minions.
TL;DR: As long as you eat the needed amount of fats and proteins, it doesn't matter if the rest of the calories come from fats, proteins or carbs, since they'll get converted to carbs anyway.
Carbs are just (relatively) easy energy. So not eating carbs means your body needs to do more work by converting fats and proteins. That can lead to tiredness and issues with physical performance.
I think its theoretically possible to live without carbs, but it brings no health benefits, because your body then converts proteins and fats to carbs.
The important thing is calories and you can eat a lot with carb-heavy meals. Fat too, since both of those are delicious. (Longer carb chains can be more filling and technically fibers are also carbs I think.)
If you want to loose weight, there are many different strategies, because in the end you have to pick a diet that you are able to follow. (I recommend this playlist by Renaissance periodization.)
The most optimal way (in the spreadsheet sense) would be to calculate how much protein and fat and total calories you need. Then you add the calories from protein and fat and fill the missing ones with carbs. Less carbs has no proven benefit.
There are many online calculators out there, that do this for you.
To loose weight, don't eat less than 500 calories a day less than your maintenance amount. But maybe start with -250 or even -100. It's also a good idea to have "rest" weeks every couple of weeks, where you eat a maintenance amount of calories to relief fatigue and stress.
Cheat meals are a terrible idea. If you loose 3000 calories over 6 days and then go goblin mode on Sundays, you can eat an extra 3000 calories or more no problem, ruining your weeks progress. Instead do the aforementioned rest weeks.
Hope this helps. Its always good to live long and healthy just to make the haters angry :P
