What you don’t know is that she and her husband have a large amount of debt. They do not live within their means and have planned very little for their retirement. You and your husband have been very responsible in your spending and retirement planning.
It is not wise to compare yourself to this woman or anyone else, because you likely don’t know the whole story.
You can always find others who are better off than you or worse off than you. It’s more important to concentrate on yourself and on being grateful for your own life.
Live your life and stop making any comparisons.
