Countries need to reduce their dependency on the US first:

• The US is the strongest force within NATO, so with Russia getting more aggressive, Europe and Canada need to quickly build up a stronger army.
• The US is NATO’s largest supplier of weapons, so Europe and Canada need to invest in their weapons industry.
• The US is the worlds largest manufacturer of CPU’s and GPU’s. While there are non-US alternatives, these are not as good and are designed for custom build electronics rather than desktops, laptops and servers.
• Most international payments go via the US (even a lot of international payments within Europe). Countries need to persuade their banks to find new ways to do international payments, but the current system is pretty advantages for the banks, so they are reluctant to agree.
• Most cloud infrastructure is in the US. Other countries will need to move their data out of the US.
• The US is a large provider of humanitarian aid, and the largest exporter of food. Poor countries will have to find a new way to get those resources.

It depends on (sub)culture, but mainly yes.

Bars were often cheap too, so going to the bar multiple times per week was not expensive. The reason these bars were cheap:

• Outside of touristic areas ground is cheap.
• If the local government allows it, the bar can on the owners property.
• The owner and customers were often friends, so friend pricing would be standard.
• Health and safety regulations used to be less strict. Allowing for lower prices.
• The bar was open whenever the owner wanted, instead of on a fixed schedule, making it more easy to combine with a second job.
• Bars rarely had a menu, they just sold whatever they had in stock. Today customers would be upset if an item on the menu was not in stock.

Also,

• Parks used to be less safe and less well maintained, so buying drinks in the supermarket and consuming them in the park wasn’t really an option.
• The internet wasn’t a thing, so people who wanted to spend the evening gaming had to do so in the bar.
