I don’t believe that there will be a serious crash. Too many politicians have their money in the markets. They won’t let it happen because it would hurt them.
And, when it's time to pull out before the crash, they will. And, leave you holding worthless paper.
Proverbs 23:4-5:
4 Do not weary yourself to gain wealth, Cease from your consideration of it. When you set your eyes on it, it is gone.
5 For wealth certainly makes itself wings like an eagle that flies toward the heavens.
It seems only the super rich are able to avoid a lot of taxes and somehow pass the burden on to the lower classes. However, it has been my observation that the government eventually gets their stuff too. Their heirs never really grow it like the original owner did. Also, in order to hold on to what one has built up, one ends up running on a treadmill like a hamster and becomes a slave of the government.
The key is to only have what you need to live and keep a low profile. Something the Apostle Paul said...
Philippians 4:11 Not that I speak from want, for I have learned to be content in whatever circumstances I am.
12 I know how to get along with humble means, and I also know how to live in prosperity; in any and every circumstance I have learned the secret of being filled and going hungry, both of having abundance and suffering need.
13 I can do all things through Him who strengthens me.
