Not really.
Let's set up a quick boundary condition. Since you mentioned most people, you're talking about the lower-middle and middle classes. Let's keep the discussion on them. The working poor have it bad almost everywhere, and I think we both agree that there's more that can be done in most countries to support them.
For someone with a median household income, it's still very much possible to finding housing that is less than 25-30% of their household income. This is true even in high cost of living (HCOL) areas. Now, there are some cities or sections of cities that are unaffordable for someone with a median income, but these are very much the exceptions.
To put it simply, if you have a median household income for your country, in almost all locations in almost all OECD countries, you earn enough to follow a household budget that allows you to save 15-20% of your take home pay. If you can't save a portion of your income and you're not living off of a below-average wage, it's very likely that you either made decisions that aren't conducive to saving (e.g., you're house poor, car poor, or your discretionary spending is too high).
> along with healthcare in the US
Quality health care is expensive in most countries. The US has its own set of issues that make health care more expensive than in most other countries (e.g., population density), but it's not orders of magnitude higher. It's also offset by the higher salaries that people in the US earn over, say, the average EU state.
