A big part of the wait times is because of the healthcare coverage IMO.
In the USA, if you have a non-life threatening issue, that is more annoying than an actual problem, it usually gets ignored because nobody wants to go into debt for that.... Unless you're a millionaire or something, I guess.
Meanwhile in countries with socialized healthcare, if you're even slightly unwell (and even in cases where you're not unwell) you can get any number of procedures done to rule out any possible illness.
There's simply no good reason to not get checked out if you feel the need to be checked out.
