What is the most recession proof business you have ever seen?

Any business that provides essential services would be quite resilient.

Essential meaning that we need it daily, regardless of the economic climate. Think about what you do daily and ideas will be there.

So we're looking at industries like Utilities, Healthcare, basic transportation, F&B to a certain extent.

I think cybersecurity and plasma business. This is those kind of resilient proof business as no matter econony up or down, the last time business will cut off is cybersecurity. More people will go for donation when there's recession to earn extra income (for US).

The education industry might be one of them as well considering how in a state of downturn, people constantly look for means and ways to stay relevant.

Additionally, our state also supports this industry with its constant advocacy for young learners and in the case for adults, a continuous learning process.

Utilities. (energy, water)

This should be the most recession proof business i can find. (lots of utility funds out there)

Even funeral home see a drop in profit as people opt for cheaper coffins and shorter period of gieving.

Utilities' returns are more or less dependable on mandated rates. To be fair, their profit margin is the same during recession OR boom. So in good times, their profit margins look sad.

There are many business that are not just recession proof but recession positive. For example during a recession, lipstick sales tend to goes up. This is because people cut down on luxury and decide to reward themselves with small luxuries like small... lipsticks.
