A more careful reading of the Bible will tell you that the Bible does not say that "rich people won't go to heaven" so much as "anyone who is fixated on riches won't go to heaven".
As Haydock’s commentary puts it: “The apostles wondered how any person could be saved, not because all were rich, but because the poor were also included, who had their hearts and affections fixed on riches.” The problem with the rich young man, then, was not that he was rich, but that he valued riches above following Christ. And that is a spiritual malady that can afflict even those who are not rich.
> And again I say unto you, It is easier for a camel to go through the eye of a needle, than for a rich man to enter into the kingdom of God.
And no, there was no city gate called "The Eye of the Needle". That was made up by people trying to convince themselves they could hoard money and still go to heaven.
When the disciples heard this, they were greatly astonished and asked, “Who then can be saved?” Jesus looked at them and said, “With man this is impossible, but with God all things are possible.” (Matthew 19:25–26, ESV)
