It's a solution if and only if the space allotted is enough for everyone on the plane to bring a decent sized suitcase. If not, then it's not a solution.
This is precisely my point. The US allows people to Carry on two giant bags, and everyone pushes the boundaries absurdly.
In other countries, the carry-on limit is strictly enforced. They have metal frames to test the size of your luggage, and if it doesn’t slip in, you ain’t taking it on the plane. And a “personal item” isn’t allowed to be a second bag the size of a carry-on suitcase.
If you have too much stuff, tough. Either take less crap or get checked luggage.
