Just take a look at the demographic shift over the last few decades. There is no denying that democrats will inevitably take over and socialism will follow.

Even if the estate tax remains the same, any mid 40s person with $1M in their retirement accounts should trip $30M by their death. That's not accounting for real estate or investments outside of retirement accounts.

Today there are 5 million couples in the US with a net worth of $5M or more. For those of them in their 40s or early 50s, they'll all probably die with a net worth of 50-100M so they will far outpace the $30M/couple limit. I also think that $30 limit will get cut to $10M or less the second we have a democrat majority.
