I don't know if I buy into the idea of a collapse but if it happened on republican President's watch just think of Herbert Hoover to the nth degree.
Satan won the right to walk the earth and have power over the earth. He is very busy. America is losing or has lost out love and faith in God Almighty. Read Revelations and mull it over for awhile.
God has made commandments to live by and for believers to have a good life. So did Jesus Christ. Still we are deceived and fail to follow what it is we say we believe.
Faith is weak for many. We have not turned to God in faith and trust and actions. Revelations and connected passages all through the Holy Bible show and tell about devastation, punishment, terror, and more. We are at choice. Get right with God, quickly. Seek forgiveness, and repent of evil In Jesus name, amen.
