Puritanism typically holds that work is required, both historically and with the remnants we might see in more conservative protestants. Love of wealth - and particularly displays of wealth - would be failures of modesty and humility which are core values. Simply having wealth, especially wealth not shown but used for charity, would be considered a result of hard work.

The puritans didn't wear drab clothes because they lacked decent dyes, they wore them as an element of modesty.

Alms to the poor was not considered a bad thing, it was religiously required, especially when used to evangelize.
