减少新内容前后的空白

Question

如何减少\begin{mq} … \end{mq}以下代码中块前后的空白？理想情况下，我希望环境与前后段落之间的空白为 1em。与环境块外的段落之间的空白相同。

\documentclass[12pt, openany]{book}

% Page Setup
\usepackage[paperheight=8in,
            paperwidth=6in,
            top=.1in,
            bottom=.2in,
            right=.1in,
            left=.1in,
            heightrounded]{geometry} 

% Set space between paragraphs
\setlength{\parskip}{1em}

% Custom Quotation Environment
\newenvironment {mq} %My Quote
{
    \ignorespaces
    \begin{list}{}
    {
        \setlength{\leftmargin}{1cm}
        \setlength{\rightmargin}{1cm}
        \setlength{\parindent}{0pt}
    }        
    \item % Inserted text 
}
{\end{list} \par \ignorespacesafterend}

\usepackage{lipsum}

\begin{document}

\lipsum[1-2]

\begin{mq}
    Average wage of employees \dotfill\ $\$\,2,200$\\
    Average salary and profit of owners \dotfill\ $\$\,26,000$\\
\end{mq}

\lipsum[1-2]

\end{document}
